Conexant Systems Inc. released what it claims as the industry's most comprehensive and feature-rich family of video encoders for notebook and desktop PCs that are fully compliant with Intel's new serial digital video output (sdvo) front-end interface.

According to Conexant's press release, the high-performance CX2590X encoder family is the first single-chip solution in the world to combine an integrated dual digital visual interface (DVI) transmitter with standard-definition (SD) and high-definition (HD) TV-out and VGA outputs that are capable of operating simultaneously and independently from one another through the Intel Graphics Media Accelerator 900 in the Intel 915G Express Chipset. This capability allows individuals to concurrently view different images on multiple display screens, added Conexant.

"Our new encoder family is an extension of our proven high-definition video encoder and DVI product lines, which allows system manufacturers to leverage a single platform for multiple applications," said Greg Fischer, VP of Convergence Video Products for Conexant. "The transition by PC manufacturers to Intel's serial bus architecture requires a subsequent transition to new devices that support sDVO," he added.

Conexant stated that the device family builds upon the legacy and success of the CX2587X HD television (HDTV) encoder and the CX2589X DVI transmitter with HDTV-out. The new chip includes six separate digital-to-analog converters that enables the simultaneous interconnect of composite, SVideo and component interfaces. Additional features include adaptive flicker filtering for enhanced image output and improved viewing quality.

Samples of the CX2590X video encoders are already available, with volume production scheduled this month. The high-performance IC is offered in several pin-compatible configurations to support a variety of display signals, with options to drive one, two or three display media simultaneously. The chip is packaged in a 14-by-14mm 128-pin exposed thin quad flat pack (ETQFP). Prices range from $6 to $7 each in quantities of 10,000, depending upon feature set.
