Recommended Circuit Schematic
The split-loaded terminations for ECL signals need to be located at the input of devices receiving those ECL signals.
The power supply ltering is required for good EMI performance. Use short tracks from the inductor L1/L2 to the module Rx Vcc.
A GND plane under the module is required for good EMI and sensitivity performance.
