ATR0874

1. Description

The ATR0874 is a Photo Detector Integrated Circuit (PDIC) for operation in high

speed DVD applications like DVD-RAM and DVD+/-RW at a wavelength of 650 nm

and CD-RW at a wavelength of 780 nm. It includes 10 channels with 4 different gain

steps. The four channels A, B, C, D are high speed channels whereas the channels

E1G1, E2G2, F1H1, F2H2 are high gain channels at average speed for tracking con-

trol, sector information etc.. The remaining two channels RF+ and RF- are RF

paraphase outputs. Channels A to D are summed together at the RF outputs.

Summary

Preliminary

Setting of the gain and entering/exiting sleep mode is controlled using the two tri-state

inputs SW1 and SW2.

All channels are set to tri-state during sleep mode.

Due to its small package size the ATR0874 is especially suited for application with low

height requirements like SLIM and UltraSLIM drives.
