DVD PRML Channel and System Controller SoC- AT78C4050
The AT78C4050 is ATMEL’s high-integration, high performance single chip solution for DVDROM, DVD-R/RW, DVD+R/RW, CD-ROM, CD-R/RW and Blue Laser formats. It integrates all required components for a DVD and CD rewritable drive as well as for a DVD recorder. The AT78C4050 includes data channel, DVD ECC, CD CIRC C3, buffer management, DVD CD 1.7PP, EFM+, EFM Endec and ATAPI interface logic.
The AT78C4050 is programmed by an external flash, and needs an external SDRAM, and a power driver to create a complete DVD/CD rewritable solution. This chip can be connected to an MPEG Endec to build a DVD recorder for consumer electronics applications.
The AT78C4050 supports various types of OPUs. Either a current output OPU or voltage output OPU can be connected to AT78C4050. ALPC, ROPC and OPC manage operation of the laser diode driver IC and control the writing process. On-chip features and programming options improve performance in high-speed systems.
