LMX2594: Can't get sysref clock to work in TICS or real life

Part Number: LMX2594

Hi,

I am trying to make a setup using 200MHz input, 10GHz fVCO (and OutA) and a system clock of 62,5MHz.

The VCO runs fine (Input: No doubler, PreR, Mult or PostR / VCO: NDivider 50, Integer Mode)

The system clock however does not run at all, and I can't set it up in TICS either.

In TICS the Included Divide is always set to 1, so the interpolator frequency is always too high, even with the Sysref-Pre-Divider set to 4 (maximum) it is still 2.5GHz.

In real life I have also tried many things, but just never get any output when I set RFoutB to SysRef. The Sysref is enabled and set to repeat, the sysrefreq pin is high.

Yours,

Marc.
