CL-CS3712

Integrated AVI/ATAPI DVD

Drive Manager Datasheet

Features

Overview

• Integrates all required components for a complete AVI

or ATAPI interface DVD drive (front-end) electronics

solution:

The CL-CS3712 is Cirrus Logic’s high-integration, high-

performance ATAPI DVD drive manager. It integrates all

required components for a DVD loader for DVD players,

game consoles, and DVD-ROM drives. The CL-CS3712

includes an RF amp, servo control processor, data

channel, DVD ECC, CSS authorization, CD-ROM

decoder, and ATAPI interface.

- RF amp

- Data channel

- Servo control processor

- DVD ECC (error correction code)

- CSS (content scramble system)

- ATAPI decoder

The CL-CS3712 can be configured with an audio DAC

(digital-to-analog converter), external buffer memory (8- or

16-bit DRAM), a local micro-controller with its RAM and

ROM, and power drivers to create a complete DVD-ROM

electronics solution.

• Reads DVD+RW, DVD-ROM, DVD-RW, CDDA, CD-

ROM, CD-R, CD-RW, VCD, and DVCD discs

• Direct Audio/Video interface for DVD player

applications

• ATAPI interface for game console and DVD loader

solutions

• High-performance controller supports DVD disc speeds

up to 8x and CD-ROM disc speeds up to 40x

• Partial Response Maximum Likelihood (PRML) data

channel

• Servo Control Processor (SCP) on-chip

• DVD navigation support

• 208-pin LQFP/EPAD packages

The CL-CS3712 supports DVD disc speeds up to 8x and

Ultra DMA host speeds up to 33.3 Mbytes/sec.

The RF signal is over-sampled by a high-speed ADC

(analog-to-digital converter). The timing loop is closed in

the digital domain with variable decimation and

interpolation used to provide the output samples to the

data recovery logic. A channel-quality logic circuit is

provided to allow parametric calibration.

The CL-CS3712 data channel supports partial response

maximum likelihood (PRML) data acquisition, providing

state-of-the-art data recognition in a noisy environment,

coming from the pick-up head.
