Description The ATR1874 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, and D are high-speed channels whereas the channels E1G1, E2G2, F1H1, F2H2 are high-gain channels at average speed for tracking control, sector information etc.
The remaining two channels RF+ and RF– are RF paraphase outputs.
