Function
Most positive power supply input.
Ground
These differential PECL 100K compatible inputs
receive NRZ data.
This PECL 100K compatible input enables
Laser Driver. Modulation current goes to zero
when asserted HIGH.
Open collector outputs from the modulation
buffer drive these differential current outputs.
Voltage reference for use with RSET.
An external resistor sets up the source current
for modulation IMOD.

NOTE:
1. Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. This is a stress rating only and functional operation is not implied
at conditions other than those detailed in the operational sections of this data sheet. Exposure to ABSOLUTE MAXIMUM RATlNG conditions for extended
