General Description

1.

CD-ROM decoder This block takes the MPEG bit stream from the external CD digital signal processor and decodes it in accordance with the CD-ROM standard.

The decoded data is automatically transferred to the next stage, the system decoder.

Overview

Ordering number :EN *5684 CMOS LSI LC74201E Video CD Decoder Preliminary Overview The LC74201E is a CMOS LSI that reduces 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.

Key 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 microcomputer.
  • Support for two external DRAM configu.
