Overview

General-Purpose Output Expander with MIPI RFFE Host Interface Evaluation Module - I2C IO Expander

The EVM operates from USB supplied power. This board supports USB to MIPI RFFE communication to support evaluation of the LM8335 MIPI RFFE to General Purpose Output (GPO) expansion.

Features
  • MIPI RFFE Interface Version 1.10 Compliant, Supports Output expansion, Host Interface address select pin:
    • ADR=GND, USID[3:0]=0001
    • ADR=VDD, USID[3:0]=1001
  • Pin-configurable initial state:
    • CFG=GND, GPO Hi-Z, with weak internal pull-down resistor enabled; GPO_OUT_DATA is unmasked
    • CFG=VDD, GPO Hi-Z, with weak internal pull-down resistor enabled; GPO_OUT_DATA is masked
  • Three sources for chip reset:
    • VIO input pin
    • POR
    • Software-commanded reset
