The SY88932L 3.3V SONET laser driver is the smallest
laser driver with programmable modulation current used for
applications up to 3.2Gbps. The device accepts either PECL
or CML level data inputs. The SY88932L provides
modulation voltage/current of up to 60mA for FP (Fabry-
Perot) or DFB (Distribution Feedback) lasers. There is a
75kΩ pull-down resistor to VEE at the input of /EN. An
active TTL enable signal shuts o the modulation current.
This document provides design and implementation
information, as well as, a detailed description of the
SY88932L evaluation board. The evaluation board is AC-
coupled, and has both dierential inputs and outputs, and
a resistor port to vary the modulation voltage.
