Tiny PCI Express broadcast decoder fits PC-based multimedia apps


Conexant Systems introduced what it is calling the industry's smallest-form-factor, PCI Express 1.0a-compliant and 1.1-ready audio/video (A/V) broadcast decoder. The CX23885 is targeted at multimedia applications such as watching television or listening to the radio on a PC.

The CX23885 is the first in a family of planned devices. The device captures and decodes both analog and digital television broadcasts, and supports worldwide audio and video standards. In addition, the single-chip solution integrates all of the functions required to perform television and external A/V capture. This flexibility provides manufacturers with economies of scale, allowing them to develop a broad range of products that support both analog and digital broadcasts in standard or high-definition formats.

The high level of audio and video integration eliminate the need for additional broadcast audio decoding and processing chips, or external sound demodulation chips. This lets developers reduce bill-of-material (BOM) costs without compromising audio and video quality. The chip is suited for regional broadcast requirements, and is backward-compatible with the company's CX25843 A/V decoder. Additional planned devices will also be offered in pin-compatible configurations.

The CX23885 is sampling now with volume production scheduled for the second quarter. The chip is packaged in a 14- by 14-mm lead-free 128-pin exposed thin quad flat pack (ETQFP), and is priced at $10 each in production quantities. Conexant offers multiple CX23885 PCI Express and ExpressCard reference designs that include schematics, layout files, and evaluation boards with production-ready device drivers.
