VSC7940 - SONET/SDH 3.125Gb/s Laser Diode Driver
The VSC7940 is a single 5V supply laser diode driver specially designed for SONET/SDH applications up to 3.125Gb/s.
External resistors set a wide range of bias and modulation currents for driving the laser.
Data and clock inputs accept differential PECL signals.
