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.
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.
