MT1336
GENERAL DESCRIPTION
MT1336 is a high performance CMOS analog front-end IC for both CD_ROM driver up to 48xs and DVD-ROM driver up
to 16xs. It also supports DVD-RAM read up to 4xs Version 2. It contains servo amplifiers to generate focusing error,
3-beam tracking error, 1 beam radial push-pull signal, RF level and SBAD for servo functions. It also includes DPD
tracking error signal for DVD_ROM application. For DVD-RAM disks, there are also Differential Push-Pull (DPP) method
for generating tracking signal and Differential Astigmatic Detection (DAD) for processing focusing signal. Programmable
equalizer and AGC circuits are also incorporated in this chip to optimize read channel performance. In addition, this chip
has dual automatic laser power control circuits for DVD-ROM (DVD-RAM) and CD-ROM seperately and reference
voltage generators to reduce external components. Programmable functions are implemented by the access of internal
register through bi-directional serial port to configure modes selection.
