GENERAL DESCRIPTION
This device is a high-end combined Compact Disc (CD) and Digital Versatile Disc (DVD) compatible 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.

FEATURES
• Compatibility 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 compatible with Philips block decoders
• Sub-CPU interface can be parallel or fast I2C-bus
• On-chip clock multiplier.
