Chrontel's New TV Encoder Chip for Mobile Devices
Posted by Darius Wey in "HARDWARE" @ 03:00 PM
"Targeted at handheld systems, a TV encoder chip dubbed the CH7023 enables mobile telephone handsets, PDAs and portable media players output video directly to a conventional NTSC or PAL television. The CH7023 video interface chip from Chrontel Inc. accepts digital input resolutions from 220 X 176 pixels up to 720 X 576 pixels, and 8, 12, 15, 16, 18 or 24-bit digital RGB or YCrCb data input. With two 10-bit high-speed DACs, the CH7023 can drive either CVBS or S-Video analog outputs. The device incorporates Macrovision copy protection, up/down pixel-by-pixel display scaling, programmable power management and adjustable brightness, contrast, hue and saturation control. The CH7023 can accommodate most input display LCD data rates, supporting pixel clock frequencies from 2- to 64-MHz. The device consumes 70-mA, and supports low-power and long battery life with I/O voltages of 1.2 to 3.3-V."
About time. With PDA TV-out solutions on the decline, the CH7023 has the potential to work wonders if used in upcoming mobile devices. Of course, the key word there is "if". I guess we'll find out soon enough as the NTSC/PAL-compatible chip should be available to manufacturers in Q2 2006 at an oh-so-wonderful bulk buy price of $3 each.
