This datasheet provides a detailed overview of the CL-CS3712, 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
The CL‑CS3712 is Cirrus Logic’s high‑integration ATAPI DVD drive manager that combines RF amp, data channel, servo control processor, DVD ECC, CSS, and ATAPI interface in a single chip. It supports DVD‑ROM, DVD‑player and game‑console applications, and can be configured with external DACs, DRAM buffers and micro‑controller interfaces.
