LMX2594EVM: No RFoutB out by SysRef input mode

Young Kim2

Part Number: LMX2594EVM

I am trying to get SysRef out from OutB_Mux=SysRef mode, but no output from RFoutB pin.

Since I attached PLL screen and register file, what could be wrong to output RFoutB by RefSys input signal with minimum delay?

Hi Young,

Did you uncheck INPIN_IGNORE?

To debug, uncheck SYSREF_REPEAT to put it in SYSREF master mode, pull the SysRefReq pin HIGH, you should get continuous 75MHz clock from RFoutB.
