ZL40514 PRODUCT PROFILE 4 Channel, Dual Output CD and DVD Laser Diode Driver with LVDS control signals

Overview
The ZL40514 is a high performance laser driver capable of driving two separate cathode grounded laser diodes (e.g. 650 nm and 780 nm laser diodes). The ZL40514 contains a 150 mA low noise read channel (ChR), and three 500 mA LVDS controlled write channels (Ch2, Ch3 and Ch4). The Read channel amplifies the positive current supplied at its reference input, INR, by a fixed factor of 100. Write channels amplify the positive currents supplied at its reference input IN2, IN3, and IN4 by a fixed factor of 240. An on-chip RF oscillator is provided for the reduction of laser mode hopping noise.
