SAN FRANCISCO In advance of the Consumer Electornics Show next week, fabless chip vendor Conexant Systems Inc. Friday (Jan. 5) unveiled a pair of new video decoders for personal video recording (PVR)-enabled set-top boxes (STBs) used to receive high-definition (HD) programming in worldwide networks.
Conexant, known mostly for its broadband communications chips, said the new devices include the CX2427X, a dual-channel video decoder that includes powerful processor and next-generation memory technology, and the CX24500, a single-channel video decoder targeted at mass market-STB devices with PVR support.
According to Conexant (Newport Beach, Calif.), the dual-channel CX2427X is capable of decoding two HDTV programs simultaneously and supporting PVR applications on two televisions. The single-channel CX24500 shares a common core architecture with the CX2427X, enabling customers to cost-effectively address multiple market segments, according to the company.
"Our new video decoder family delivers unmatched performance, and provides manufacturers and operators with a cost-effective solution for single and dual-room HDTV receivers used in any type of broadcast network," said Lewis Brewster, executive vice president and general manager of Conexant's broadband media processing business, in a statement. Consumers, he said, would also benefit because the devices will enable operators to deliver a range of HD and PVR-enabled set-top boxes at a lower cost point.
The CX2427X and CX24500 are based on the ARM 1176 processor and include a double data rate memory (DDR2) interface with unified memory and an integrated level two (L2) cache, according to Conexant. The devices each include three universal serial bus (USB) ports, integrated audio digital-to-analog converters (DACs), multiple video outputs including high-definition multimedia interface (HDMI) 1.3 with high-bandwidth digital content protection (HDCP) 1.2, and two Ethernet media access controllers (MACs) with a media independent interface (MII), the company said.
The CX2427X and CX24500 are sampling now, Conexant said, with volume production planned for the third quarter. The CX2427X is packaged in 913-pin ball grid array (BGA), and is priced at $40 per unit in production quantities, Conexant said. The CX24500 is packaged in a 736-pin BGA and is priced at $30 per unit in volume quantities, the company said. Complete reference designs are also available, the company said, bundled with a range of operating systems, middleware, drivers and development tools.
