Question - Transceiver Native PHY

Hi-Everybody

I use 3 IPs
Transceiver Native PHY + Reset Controller + fPLL
This Design is Transmitter only, and parallel 40 bit

In Transceiver Native PHY, "tx_clkout" is used as a clock for tx_parallel_data

I shot "tx_clkout" with a scope.
in the fPLL 2GHz, x_clkout = 100MHz

So I thought.
If you receive 40 bits in parallel at 100Mhz,
Serial should be 4GHz.

Therefore, the clock frequency is increased to 4GHz. (fPLL)
Then it was x_clkout = 200 MHz.

How to set the clock frequency?

I tested the frequency below
4GHz tx_clkout:200MHz
2GHz tx_clkout:100MHz
1GHz tx_clkout:50MHz
