VSC7992
10.7 Gb/s RZ or NRZ Laser Modulator Driver
GENERAL DESCRIPTION:
The VSC7992 is a 10.7 Gb/s laser diode modulator driver with direct
access to the laser modulation transistors. Laser modulation
currents are set by external components allowing precision
monitoring and setting of current levels. Clock and data inputs are
differentially terminated to 50 ohm. Both Return-to-Zero (RZ) and
Non-Return-to-Zero (NRZ) data formats may be generated. The
VSC7992 is available in a 22-pin ceramic package or in die form.
