Hi nasser
Thanks for the reply.
What should be the frequency of input reference clock?
And as per our application, we shall use 3 no of tlk10031 (one is master and another two are slaves).
The low side signals are connecting via mux, so that master can be connected to either of slaves.
While connecting to mux should be connect the reference clock out also?
What is the impact / use of reference clock out?
Hi,
The REF_CLK frequency depends on desired data rate. Please refer to the product datasheet. Below is example for 10G-KR and SFI.

Are you planning on using the recovered clock output? If not you may pull to GND via 50ohm. See below from datasheet.
Channel Output Clock. By default, this outputs is enabled, and outputs the high speed side recovered byte clock (high speed line rate divided by 16 or 20). Optionally, they can be configured to output the VCO clock divided by 2. (Note: for full rates, VCO/2 pre- divided clocks will be equivalent to the line rate divided by 8; for sub-rates, VCO/2 pre- divided clocks will be equivalent to the line rate divided by 4). These CML outputs must be AC coupled.
During device reset (RESET_N asserted low), pin-based power down (PDTRXA_N asserted low), or register-based power down, these pins are floating.

Hi Rodrigo Natal,
Thanks for the reply.
Can you please suggest the Oscillator for Reference clock input?
Hi,
TI has a lot of oscillator options in our portfolio. See below link for one example.
