How to use Shared pll in LVDS transmiter and resceiver functions

The Transmiter settings:

1.number of channes:3

2.deserialization factor:20

3.output data rate:800Mbps

4.clock frequency:100MHz

5.use shared pll(s) for Rx and Tx

The Receiver settings:

1.number of channels:1

2.deserialization factor:20

3.input data rate:800Mbps

4.clock frequency:100MHz

5.use shared pll(s) for Rx and Tx

I connected the rx_inclock and tx_inclock to a single clock source, but there needs 2 plls, seems that no merge action done.
