PDIC for DVD±R/RW and RAM
Preliminary
CXA2726GA
Pr eliminary
Description
The CXA2726GA is a PDIC (photodetector IC) developed as a photodetector for the optical pickup of
DVD±R/RW and RAM drives.
The photodiode and circuits operate at high speed to allow high-speed read and write. This IC also has a sleep
function and small COB (Chip On Board) package.
(Applications: Optical pickups for DVD±R/RW and RAM)
Features
Wide band (120MHz)
RF differential output (Read Mode: A to D signal addition output)
WPP output (WPP1 = A + B, WPP2 = C + D signal addition output)
Mode switching function (6-Mode switching + Power save mode: SW1, SW2)
12-division photodiode supporting DPP
Small COB package of Land Grid Array type
Sleep function (Power save mode)
Package
18-pin LFLGA (Plastic)
Structure
Bipolar silicon monolithic IC
