ZL40518 - 3 Channel Laser Diode Driver

General Description

The ZL40518 is a laser diode driver for high speed operation of a grounded laser diode.

The driver consists of 3 controllable channels: a switchable, low noise, read channel and two switchable write channels.

Write current pulses are enabled with the application of a low signal on the /EN pins.

Key Features

  • Current-controlled Output Current source Output Current per Channel to 250 mA Total Output Current to 300 mA Rise Time 1.0 ns, Fall Time 1.1 ns On-chip RF Oscillator External Resistor Control of Oscillator Swing and Frequency 200 to 500 MHz Oscillator Range 100 mA Maximum Oscillator Swing Single +5 V Power Supply (±10%) Low-power Consumption Common Enable, Disable Inp.
