TLK2711-SP: clock needed for Deserializer

Part Number: TLK2711-SP

Dear Friends, Looking for your help.

We are building a setup to communicate between two TLK2711 IC’s. One TLK will act as a Serializer and the other one will act as a De-serializer.  The block diagram of our design is attached.  

In the block diagram of TLK 2711 (Page : 13 of https://www.ti.com/lit/ds/symlink/tlk2711-sp.pdf?ts=1609929945730&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FTLK2711-SP) it shows that TXCLK is connected to Clock Synthesizer which is further connected to Interpolator and Clock Recovery in the RX chain(De-serializer part). Our question is that, do we really need to provide TXCLK to the TLk2711 which is just acting as a Deserialiser? If yes then is it just a reference clock of 100 MHz or do we need to provide the clock of same frequency which is being used on the Serializer side?
