LC74201JE General Description
The LC74201JE is a CMOS IC that integrates the signal processing functions required of a video CD decoder to a single chip. All that it takes to make a version 1 or version 2 video CD player is the addition of a CD digital signal processor, DRAM, an audio D/A converter, digital video encoder, and similar components.

LC74201JE Features
• Incorporation of virtually almost all the functionality required by a video CD player from the CD-ROM decoder through
to the MPEG audio and video decoders in a single chip
• Fully automatic playback with automatic decoding within the LSI in response to simple external commands and the
MPEG bit stream
• Special playback functions are activated by command inputs, and do not require signal processing by the host
icrocontroller
• Support for two external DRAM configurations: 4 M bits (256k×16 bits) or 4 M bits (256k×16 bits) + 1 M bit (64k×16
bits)
• Support for a Track 1 DRAM user area (i.e., sector buffer) of up to 8 k bytes (4 M bits of external DRAM) or 22 k bytes
(4 M +1 M bits of external DRAM)
• Automatic synchronization of audio and video
• Built-in high-speed decoder core that supports variablespeed video playback at up to quadruple speed. Audio
support for normal and double-speed playback.
• Internal registers that offer configuration settings for connecting to most commercially available CD digital signal
processors and D/A converters
• Compatible with version 2 of the video CD standard. Support for superimposition of closed caption data on the
output signal as specified in the EIA608 standard
• Support for Photo CD standard. (Base/4 and Base/16)
