Conexant video encoders enable HDTV display in TV receivers

The CX25872/3 and CX25874/5 combine adaptive flicker-filtering, HDTV-output capability and the latest copy-protection features for digital content, enabling users to display high-quality content from PCs, STBs, progressive DVD players and video game consoles on either analog or digital TV receivers.

The 64-pin TQFP devices feature high-performance TV-out capability with 10-bit DACs, programmable overscan compensation capability ranging from 0 to 25 percent and a resolution range of 320x200 pixels to 1,024x768 pixels.

The CX25874/5 complement the CX25872/3 with the addition of true HDTV display and conforms to the 525p/625p copy-protection standard. In addition, the CX25873 and CX25875 also comply with Macrovision 7.1.L1. The CX25872 and CX25874 are designed for applications that do not require Macrovision copy protection.

The CX25874/5 also integrate the CGMS standards and support 480p, 720p and 1080i Advanced Television Systems Committee standards, and provide triple-level syncs and broad pulses required to connect directly to a digital TV receiver.

The video encoders support NTSC, PAL and SECAM, as well as WSS for 16:9 TV receivers as outlined in by the EIAJ CPR-1204 and ITU-R BT.119 standards. The devices also conform to the CCIR656 and CCIR601 standards.
