RFSoC zcu111 - Incorrect Clock Out frequency

I am trying to bring-up ADC on ZCU111 in a standalone design. Configured LMX2594 using SCUI for both cases below

1. ADC with PLL

2. ADC without PLL

I both cases I get incorrect frequency on "Clock Out" port of ADC IP

Expected frequency: 32MHz (4.096 GSPS)

Observed frequency: 29.90MHz

This happens for other sampling rates also. Did anyone also see this behavior? Please help.
