1. Outline

These specifications are hardware specifications of Net Vision Co., Ltd. made NV012-A "FPD-Link

III serialize board." NV012-A is a video conversion board for changing from FPD-Link III standard

into a parallel signal. Togeter with SV series (SVM-03/03 U/SVI-06 etc.) of our company, you can

capture FPD-Link III video into PC easily.

[Fig. 1] Block diagram

The block diagram of this board is shown in [Fig. 1]. This board carries Texas Instruments

deserializer IC DS90UB914 A-Q1, Serial - parallel conversion of the FPD-Link III picture signal to

the 100 MHz of maximum pixel clock and the I2C communication through a FPD-Link III signal wire

are possible. The output connector of the parallel signal serves as an interface common to SV series,

and SV board and the use linked directly are possible. The connector of a FAKRA standard is used

for the input of a serial signal (single-ended transmission), and it is ideal for connection with the

camera of an in-vehicle use.

It is this board to [Fig. 2] SVM-03 the diagram figure at the time of connecting with a board is

shown. It becomes the same diagram also when it connects with SVI-06 etc.

[Fig. 2] Diagram

It is this board and SVM-03 to [Fig. 3]. The board connection image of a board is shown. As shown in

a figure, both boards are connected through the pin socket (CN2) of 50 pins. Since a screw whole position

is common to both boards, it can fix both boards by a spacer etc. The arrangement plan of the connector

of this board is as being shown in [Fig. 4]. The clause of "the details of a connector" shows the pin

number of a connector, and pin assignment later.

2. Details

2.1. Power system

1.8V regulator (LDO) is carried in this board, and this supplies the power supply to the core voltage

of deserializer IC. Power supply (core voltage, IO voltage) of IC It supplies from SV board of SVM-

03 etc. through connector CN2. At this time, VDDH and VDDL of SV board correspond to the core

voltage and IO voltage of this board, respectively. Usually, both VDDH and VDDL are set as 3.3V.

Moreover, in this board, the power supply for cameras can be superimposed on a FPD-Link III cable.

This power supply is supplied from CN5, CN6, or CN8. Since the power supply for cameras and IC

are divided in direct current through the capacitor, an injection order of the power supply of IC and

the power supply for cameras is not asked.

The block diagram of the electric power system of this board is shown in [Fig. 5]. When using DC

jack (CN6) which connects an AC/DC adaptor, in this board, in preparation for future extension, the

pattern of DC converter in which 12V input is possible is prepared, and voltage is changed by jumper

resistance mounted on the board. With NV012-A Since the jumper is set to the DC jack side, a

camera power supply can be supplied via DC jack by mounting CN6.

2.2. I2C function

Deserializer IC (DS90UB914A) of this board has I2 C bus, and has an I2C communication function

with serializer and the target device which let the setting change in IC, and a FPD-Link III cable

pass. In this board, since the pull-up of the I2 C bus of DS90UB914A was carried out to IO voltage by

4.7kΩ and also it is directly linked with the connector for SV series, I2C communication is possible



8

for it by the standard function of SV series as it is. Simultaneously, since I2 C bus is directly linked

with the I2C input and output connectors (CN4) on a board, connection with an external device and

the operation from an external master are also attained.

At this board, the I2C address of DS90UB914A can be changed by a DIP switch setting (SW1). For

details, please refer to the section of a DIP switch setup.

* Apply a mounting state on NV012-A version.

A camera power supply input connector (CN5, CN6, CN8) inputs DC power supply superimposed

on a FPD-Link signal wire if needed. Please input a power supply from one of connectors according

to application or a system. Required power supply capacity is dependent on the characteristic of a

target device (camera).

Extended connectors (CN7, CN9, and CN10) are the communication between boards by a multi-

channel taking-in system, and a connector for future extension. I2C input and output connectors

(CN4) are directly linked with I2 C bus of DS90UB914A,
