INTEGRATED CIRCUITS DATA SHEET SAA7335 DSP for CD and DVD-ROM systems Preliminary specification File under Integrated Circuits, IC01 1997 Aug 11 Philips Semiconductors Preliminary specification DSP for CD and DVD-ROM systems Features - patibility with CD-I, CD-ROM, MPEG-video DVD-ROM and DVD-video applications - Designed for very high playback speeds - Typical CD-ROM operation up to n = 12, DVD-ROM to n = 1.9, maximum rates (tbf) - Matched filtering, quad-pass error correction (C1-C2-C1-C2), overspeed audio playback function included (up to 3 kbytes buffer) - Lock-to-disc playback, Constant Angular Velocity (CAV), pseudo-Constant Linear Velocity (CLV) and CLV motor control loops - Interface to 32 kbytes SRAM for DVD error correction and de-interleave - Sub-code/ header processing for DVD and CD formats - Programmable HF equalizer - In DVD mode it is still patible with Philips block decoders - Sub-CPU interface can be parallel or fast I2C-bus - On-chip clock multiplier. GENERAL DESCRIPTION This device is a high-end bined pact Disc (CD) and Digital Versatile Disc (DVD) patible decoding device. The device operates with an external 32 kbytes S-RAM memory for de-interleaving operations. The device provides quad-pass error correction for CD-ROM applications (C1-C2-C1-C2) and operates in lock-to-disk, CAV, pseudo CLV and CLV modes.
