PNX7850

www.DataSheet4U.com Nexperia PNX7850 The Philips Nexperia PNX7850 is a highly integrated, multi-functional processor for high-speed DVD/CD recorders. As part of the Philips DVD+RW chipset, the PNX7850 brings industry-leading speed and accuracy to computing applications. High-speed DVD+R/RW and CD-R/RW processor for PC-hosted recorders Semiconductors The Nexperia PNX7850 processor handles all of the encoding and decoding functions required for industry-leading write and read performance in DVD/CD recorders. In addition to a 32-bit MIPS RISC core, it integrates channel and data-block codecs, a servo DSP, a buffer manager, and an audio processor. On its own, the PNX7850 can support write speeds of 8x DVD and 48x CD (early versions support 4x DVD), and read speeds of 16x DVD and 56x CD. When configured with the Philips DVD+RW chipset, the PNX7850 contributes to write performance of 8x DVD+R, 4x DVD+RW, 32x CD-R, and 12x CD-RW, and read performance of 16x DVD-ROM and 48x CD. Exceptional write speeds are due in part to a technology, developed in partnership with Intersil, that moves the writestrategy function off-chip onto the optical pickup unit (OPU).
