I need advice to how to schematic entry on these 2 units TRF3765.

Hi Yeow,

You may refer to the TRF3765 EVM schematic and layout for reference

The 4 wire interface is the same as any standard Serial Interface.

The two TRF3765 can share the same DATAIN, DATAOUT, and CLOCK line. The latch enable is addressing to either TRF3765 #1 or TRF3765 #2 from your microprocessor. They will need to have two separate lines to two different TRF3765.
