Pin description
These pin are the module’s ground connections.
They should be connected to a low impedance ground plane (0V).
This is the power supply pin for the module.
It should be connected to +5.0V.
Recommended power supply decoupling.
There are Data output pin (Differential PECL output).
Signal level of these pin are PECL level.
Refer to electrical interface in NOTE4.
There are recovered clock output pin (Differential PECL output).
Signal level of these pin are PECL level.
Refer to electrical interface in NOTE4.
When the optical input signal fall bellow the SD threshold level, The Signal Detect
is deasserted and its output logic level changes form a PECL HIGH to PECL LOW.
Signal Detect pin is differential PECL output pin.
Refer to electrical interface in NOTE5.
This pin supplies the bias for the PIN Photo Detector and it should be connected to
+5.0V.
Additionally, by using External Resistor in series with this pin, it is possible to
measure the photocurrent.
Refer to electrical interface in NOTE8.
These pin are No user connection and should be left open.
