LMK04828: lmk04821 clkin0 registers setting required

Part Number: LMK04828
Other Parts Discussed in Thread: CDCM6208

Hi Shawn,

The Clkin0 is driven by 122.88MHz clock from CDCM6208.

An oscillator is connected to the OSCIN input of the clock chip.

The issue is,

When we use the CLKIN0, we are observing carrier offset at the output of the front end RF circuit.

Where as while we use the OSCIN input we are not seeing the carrier offset. The RF output is OK, without any problem. The register values are attached. Kindly let us know the update required. In the actual system, the clock input is to CLKIN0. Kindly reply.

Regards,
