PRELIMINARY DRAFT www.cirrus.com Overview Features Block Diagram • Integrates all required components for a complete AVI or ATAPI interface DVD drive (front-end) electronics solution: -RF amp - Data channel - Servo control processor - DVD ECC (error correction code) - CSS (content scramble system) - ATAPI decoder • 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 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. 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. 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.
