*: The falling edge of Cki clock input signal is at the Di data eye pattern crossing point.
**: When open (or low) the module is in the operating mode. When high the module operates in non
clocked mode.
***: When high the module in the shut down mode (no optical output power).
When open (or low) the module is in the operating mode.
****: Vcc-Vee; with Vcc at +5V Vee must be at 0V; with Vee at -5.5V Vcc must be at 0V
*****: When provided a digital alarm indicates that the laser is degraded.
The active level is a low level.
This pin must be teidto Vcc through a 100k ohm resistor when the digital alarm is not proved

DTV / NIC Decision Threshold Voltage #
*: This pin is Not Internally Connected(NIC) in case of the high voltage generator is inside the module.
**: Package is at same potential as GND .
***: LPA output is a logic level that indicates the presence or absence of a sufficient optical input level.
A logical high level indicates an input optical level too low.
#: This pen is not internally connected if the amplitude decision threshold is not made adjustable.
##: This pen is not internally connected if the Optical Input Light Voltage functionality is not provided.
