Description
The CXD1856Q/R 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
Block Diagram
Structure
Silicon gate CMOS IC
Applications
Video CD players, MPEG1 decoder boards, etc.
