General Description

The ZL40539 is a high performance laser diode driver capable of driving two separate cathode grounded laser diodes (e.g., 650 nm and 780 nm laser diodes).

The ZL40539 contains a 150 mA low noise read channel (ChR), and three >450 mA write channels (Ch2, Ch3 and Ch4).

Each channel amplifies the positive current supplied at its reference input (INR, IN2, IN3, IN4) by a fixed factor of 100, 250, 150 and 100 respectively.

Key Features

  • Pin compatible with EL6839 Dual output for CD/DVD laser LVDS control signal, internal 100 ohms Rise time 1.0 ns, Fall time 1.1 ns typical Low noise read channel with gain of 100x to 150 mA Channel 2 gain of 250x to 550 mA Channel 3 gain of 150x to 500 mA Channel 4 gain of 100x to 450 mA Combined total output current 700 mA On-chip oscillator with frequency and amplitu.
