Not using Rx section of Lime LMS6002D


We only plan to use the Transmit section of the Lime LMS6002D SDR. So my question is do I keep the pins associated with the Receive section not connected or shorted to ground?

For example:

  1. RXINP &N are the RF inputs to the LNA’s. Should I leave them not connected or connect to ground?
  2. How about RXEN and RX_CLK, leave not connected?
