VSC7938 Laser Diode Driver

The VSC7938 is a single 3.3V or 5V supply laser diode driver specially designed for SDH/SONET 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. The automatic power control (.
