High-Performance HDMI Receiver (ADV7842)

The video interface consists of the ADV7842 dual HDMI fast switching receiver with video and graphics digitizer and 3-D comb filter. This device interfaces to the processor’s parallel peripheral interface (PPI). It operates in 24-, 16- or 8-bit modes. YCbCr and RGB video modes are supported.

The ADV7842 receiver is a high quality, single-chip, 2:1 multiplexed HDMI receiver and graphics digitizer with an integrated multi-format video decoder.

The ADV7842 receiver uses external 256 Mb DDR SDRAM for 3-D comb and frame synchronizer.

The ADV7842 receiver incorporates a dual input HDMI 1.4-compatible receiver that supports all HDTV formats up to 1080p and display resolu-tions up to UXGA. It also incorporates Xpressview fast switching on both input HDMI ports. Using the Analog Devices hardware-based HDCP engine that minimizes software overhead, Xpressview technology allows fast switching between any HDMI input ports in less than one second.

HDCP 1.4 support with internal HDCP keys. There is a version of the product, where the ADV7842 device is programmed with internal HDCP keys (ADZS-DECODEK-EX3). Consumers must have HDCP adopter status (consult Digital Content Protection, LLC for licensing require-ments) to purchase any components with internal HDCP keys. In order to interface with consumer electronics, a board with internal HDCP keys is required.

The ADV7842 receiver supports all mandatory HDMI 1.4 3-D TV for-mats in addition to all HDTV formats up to 1080p.

The ADV7842 receiver also integrates an HDMI v1.4 CEC controller that supports the capability discovery and control (CDC) feature.


Expansion Interface III

The ADV7842 receiver offers a flexible audio output port for the audio data decoded from the HDMI stream.

ADV7842 receiver can be configured to generate an interrupt based on various events. The TWI port is used for communication between the receiver and processor. The parallel peripheral interface (PPI) is used to receive video data. The serial port (SPORT) is used to receive audio data. An interrupt signal from the receiver is connected to a GPIO signal on the processor. The GPIO signal is configured via a software switch. Refer to “Video Decoder EI3 Extender Board Schematic” on page B-1 for more information.

For more information about the ADV7842, go to www.analog.com and search for ADV7842.

An example program demonstrating capabilities of the ADV7842 device is available by installing the Video Decoder EI3 Extender Board Support Package (BSP).

Expansion Interface IIIThe Expansion Interface III (EI3) allows an extender board to be used across various hardware platforms that have the same expansion interface connectors.

The EI3 implemented on the Video Decoder EI3 Extender Board contains the PPI, SPORT, TWI and GPIO ports. These signals are used for the peripherals on the extender. The connectors contain a majority of the pro-cessor’s signals. For pinout information, go to “Video Decoder EI3 Extender Board Schematic” on page B-1. The mechanical dimensions of the expansion connectors can be obtained by contacting “Technical Support”.

The Video Decoder EI3 Extender Board can interface with EZ-KIT Lites/EZ-Boards operating at an IO voltage of 3.3V. Other IO voltages




are not supported. The extender can be powered from either the EZ-KIT Lite/EZ-Board or through the on-board 5V power connector (P1).

For more information about extender boards, visit the Analog Devices Web site (www.analog.com).

Limits to current and interface speed must be taken into consideration when using the EI3. Current for the EI3 can be sourced from the EZ-KIT Lite/EZ-Board; therefore, the current should be limited to 200 mA for 5V and 300 mA for the 3.3V planes. If more current is required, then a sepa-rate power connector and a regulator must be designed on the daughter card. Additional circuitry can add extra loading to signals, decreasing their maximum effective speed.

Analog Devices does not support and is not responsible for the effects of additional circuitry.

Video Decoder EI3 Extender Board Hardware Reference

Software-Controlled Switches (SoftConfig)

On the Video Decoder EI3 Extender Board, all of the traditional mechan-ical switches and jumpers have been replaced by I2C software-controlled switches. Refer to any SoftConfig*.c file found in the installation direc-tory of CCES for an example of how to set up the SoftConfig feature of the product through software.

The SoftConfig section of this manual serves as a reference to any user that intends to modify an existing software example. If software provided by ADI is used, there should be little need to reference this section.

Care should be taken when changing SoftConfig settings not to create a conflict between interfaces.

Overview of SoftConfigIn order to further clarify the use of electronic single FET switches and multi-channel bus switches, an example of each is illustrated and com-pared to a traditional mechanical switching solution. This is a generic example. After the generic discussion, there is a detailed explanation of the SoftConfig interface specific to the extender board.

Figure 2-2 shows two individual FET switches (Pericom PI3A125CEX) with reference designators UA and UB. Net names ENABLE_A and ENABLE_B control UA and UB. In this example, the default FET switch enable settings are controlled by resistors RA and RB which pull the enable pin 1 of UA and UB to ground (low). In a real example, these enable signals are controlled by the Microchip IO expander. The default pull-down resistors connect the signals EXAMPLE_SIGNAL_A and EXAMPLE_SIGNAL_B and also connect sig-nals EXAMPLE_SIGNAL_C and EXAMPLE_SIGNAL_D. To disconnect EXAMPLE_SIGNAL_A from EXAMPLE_SIGNAL_B, the Microchip IO expander is used to change ENABLE_A to a logic 1 through software that interfaces with



the Microchip. The same procedure for ENABLE_B disconnects EXAMPLE_SIGNAL_C from EXAMPLE_SIGNAL_D.

Figure 2-2. Example of Individual FET Switches

Figure 2-3 shows the equivalent circuit to Figure 2-2 but utilizes mechan-ical switches that are in the same package. The default is shown by black boxes located closer to the ON label of the switches. In order to disconnect these switches, physically move the switch to the OFF position.

Figure 2-3. Example of Mechanical Switch Equivalent to Figure 2-2



Figure 2-4 shows a bus switch example, reference designator UC (Pericom PI3LVD512ZHE), selecting between lettered functionality and numbered functionality. The signals on the left side are multiplexed signals with naming convention letter_number.

Figure 2-4. Example of a Bus Switch

The right side of the circuit shows the signals separated into letter and number, with the number on the lower group (eg. 0B1) and the letter on the upper group (eg. 0B2). The default setting is controlled by the signal CONTROL_LETTER_NUMBER which is pulled low. This selects the number sig-nals on the right to be connected to the multiplexed signals on the left by



default. In this example, the Microchip IO expander is not shown but controls the signal CONTROL_LETTER_NUMBER and allows the user to change the selection through software.

Figure 2-5 shows the equivalent circuit to Figure 2-4 but utilizes mechan-ical switches. Note the default for reference designators SWC and SWD is illustrated by black boxes located closer to the ON label of the switches to enable the number signals by default. Note the default setting for refer-ence designators SWE and SWF is OFF. In order to connect the letters instead of the numbers, the user physically changes all switches on SWC and SWD to the OFF position and all switches on SWE and SEF to the ON position.

Figure 2-5. Example of Mechanical Switch Equivalent to Figure 2-4



Programming SoftConfigOn the Video Decoder EI3 Extender Board, a single Microchip MCP23017 device controls individual and electronic bus switches via TWI. The device has the following programming characteristics:

• There are two programmable GPIO registers.

GPIO Register Register Address

GPIOA 0x12

GPIOB 0x13

• Each GPIO register controls eight signals (software switches).

• By default, the GPIO signals function as input signals; therefore, all electronic switches are in the OFF state.The signals must be programmed as output signals to override their default values. The following table shows the Microchip register addresses and values that must be written to them to program the signals as output signals.

IODIR Register IODIR Register Address Value to be Written to Program Signals as Outputs

IODIRA 0x00 0

IODIRB 0x01 0

Each example in CrossCore Embedded Studio includes source files that program the soft switches, even if the default settings are being used. The README for each example identifies only the signals that are being changed



from their default values. The code that programs the soft switches is located in two files:

• SoftConfig_Decoder.c for configuring the extender board

• SoftConfig_xxx.c for configuring the EZ-KIT Lite/EZ-Board; xxx identifies the EZ-KIT Lite/EZ-Board file in each example.

Page 2 of “Video Decoder EI3 Extender Board Schematic” on page B-1 shows how the GPIO expanders are connected to the board’s ICs.

U12 is a 24-bit bus switch. The switch connects the decoder to the processor.

U8–9 are 2-port bus switches. The switches select the GPIO signals to be used as the interrupt for the ADV7842 device (U10).

U18 is an 8-port bus switch. The switch is used to connects/disconnect the SPORT interface of the processor to the ADV7842 receiver.

Table 2-1 and Table 2-2 show the output signals of the GPIO expander (U2) with a TWI address of 0100 110X, where X represents the read or write bit. The signals that control an individual FET have an entry under the FET column. The Component Connected column shows the board IC that is connected if the FET is enabled.

Composite Cable KOBICONN 17FH101

Power Connector (P1)Under normal circumstances, the power connector is not needed because the Video Decoder EI3 Extender Board derives its power from the EZ-KIT Lite/EZ-Board. If the EZ-KIT Lite/EZ-Board is not able to sup-ply enough power to the Video Decoder EI3 Extender Board, then an external power supply can be connected to P1 and power the extender and EZ-KIT Lite/EZ-Board.
