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 filtering is required for good EMI performance. Use short tracks from the inductor L1/L2 to the module Rx Vcc and Tx Vcc.
A GND plane under the module is required for good EMI and sensitivity performance.
