MPEG1 Decoder

CXD1852Q

Description

The CXD1852Q is a single-chip MPEG1 decoder

with a built-in CD-ROM decoder which allows

decoding of MPEG1 system, video and audio layers.

A built-in CD-ROM decoder enables direct connection

with a CD-DSP. Combining this chip with a control

microcomputer and 4-Mbit DRAM, etc. allows

configuration of a MPEG1 decoding system for video

CD players, etc.

Features

• Supply voltage: 3.3 ± 0.3V

• Input and output voltages: LVTTL compatible

• 5V can be applied as the input voltage (excluding

some pins)

• Allows decoding of MPEG1 system, video and

audio layers

• Built-in CD-ROM decoder allows direct connection

with a CD-DSP

• CD-ROM decoded output can be transferred to

and stored in an external DRAM

• RGB and YCbCr video data output allowed

• Built-in video sync generator

• Audio data output can support various DAC

• Supports various special playback modes

• Video CD PAL high resolution still picture can be

decoded with a single 4-Mbit DRAM

• 8-bit parallel and 4-line serial host interfaces

• CD-DA through operation allowed
