USB 1.1 PHY IP for IOT and Low Power application
Overview
M31 provides customers a unique USB 1.1 PHY IP for IOT application. The USB 1.1 PHY
IP incorporates a semi-digital PLL which can supports clock inputs as low as 32.768KHz.
The USB 1.1 PHY IP not only supports the standard USB 1.1 functions but also provides
multiple clock outs ranged from 48MHz to 240MHz. It’s extremely suitable for IOT devices
or wearable devices which may need the basic USB functions.
Highlights
Worldwide smallest USB 1.1 PHY IP with PLL inside (<0.1mm²)
Fully compliant with Universal Serial Bus (USB) 1.1 electrical specifications
Integrated PLL to provide a variety of stand-alone clock outputs

BCK Technology Specialized for Peripheral Applications
M31 provides customers with not only a standard USB PHY solution, but also
a unique BCK (Built-in-Clock) function to eliminate the need of external crystal
oscillator. The IP processes background calibration during USB data transfer to
ensure frequency accuracy. The USB IP with BCK can meet the USB-IFcompliance
spec and exhibit the same electrical performances as the standard USB IP.
Highlights
Fully compliant with Universal Serial Bus (USB) 3.0, 2.0 and 1.1 electrical specifications
Supports clock inputs from internal BCK module
Real-time calibrations to assure the frequency accuracy
