How to use Shared pll in LVDS transmiter and resceiver functions

In my design,

for LVDS Transmiter, the tx_inclock is 40MHz, deserialization factor is 20, so tx_outclock is 800M .

for LVDS Receiver, it will receive signal from the LVDS Transmiter.thus,rx_inclock should be 800M, deserialization factor is 20, rx_outclock is 40MHz.

So, the tx_inclock and rx_inclock are different in my design, how can i use the shared PLL function to reduce the resource usage. Thanks!
