Figure 1: Recommended Transceiver and Receive Data Terminations
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.

Signal Detect
The C-1xx-1250AC-FDFB-SLCx transceivers are equipped with LVTTL signal detect output. The standard LVTTL output

Power Coupling
A suggested layout for power and ground connections is given in figure 3A below. Connections are made via separate voltage and
ground planes. The mounting posts are at case ground and should not be connected to circuit ground. The mounting posts are at case ground
and should not be connected to circuit ground. The ferrite bead should provide a real impedance of 50 to 100 ohms at 100 to 1000 MHz. Bypass
capacitors should be placed as close to the 10-pin connector as possible.
