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.
