DS90UB941AS-Q1: RefClock for Independent 2:2 Mode

Part Number: DS90UB941AS-Q1

Experts, 

For DS90UB941AS-Q1 Independent 2:2 Mode, one screen is 1080p, another screen is 720p. Can DOUT0 PCLK take from DSI0 ref and DOUT1 PCLK take from DSI1 ref with different PCLK to compensate different screen?

great thanks

    Hello Ryan,

    For using the 2:2 Mode, you do require an external reference clock provided to the REFCLK0 pin is the reference clock for the FPD-Link III Port0
    interface, while an external reference clock provided to the REFCLK1 pin is the reference clock for the FPD-Link III Port1 interface.
