Integrated ATAPI DVD Drive Manager

The CL-CR3710 is Cirrus Logic's high-integration, high-performance ATAPI DVD drive manager. It integrates all required components for a DVD loader for DVD players, and slim-line DVD-ROM drives. The CL-CR3710 includes RF amp, servo control processor, data channel, DVD ECC, CSS authorization, CD-ROM decoder, AVI, and ATAPI interfaces.

The CL-CR3710 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 player electronics solution. It has an integrated MPEG-2 interface and can be efficiently designed into a DVD system.

The CL-CR3710 supports DVD disc speeds up to 8x and Ultra DMA host speeds up to 33.3 Mbytes/sec.

The host interface is designed with AVI and ATAPI interfaces. The AVI interface supports either serial or 8-bit parallel streams for compliance with Type-A or Type-B MPEG interfaces. The ATAPI Command and Control Block registers are contained in the CL-CR3710 register set, which allows both host and local micro-controller access. Either interface is enabled by setting a bit in a register.
