Dallas Extending its line of mixed-signal video ICs, Texas Instruments Inc. (TI) today introduced a pair of 8- and 10-bit triple analog-to-digital (A/D) converters that provide up to 165 Msamples/second.
The TVP700x series offers improved jitter-reduction performance, higher image quality in video systems, and the ability to support the increased bandwidth needed from PC and high definition (HD) video output, said Frank Moizio, TI's worldwide strategic marketing manager for digital light processing (DLP) front projection. “Both of these devices are fully compatible with current DLP imaging ASIC products providing up to UXGA resolutions and 1080 progressive analog HD support,” he said.
Applications include business projectors, televisions and set-top boxes.
The TVP7000, featured on the DDP2000 DLP reference design, provides sampling rates up to 150 Msamples/s and supports 1080p video inputs. The TVP7001 is available with the DDP3020 DLP reference design and delivers up to 165 Msamples/s and increases PC graphics output to 1600 x 1200 at 60 Hz ultra extended graphics array (UXGA) quality. The two devices also support a 10-bit mode up to 110 Msamples/s.
Both video converters offer integrated phase-locked loops (PLL) for pixel clock generation, including 12-165 MHz (12-150 TVP7000) pixel clock generation from horizontal synchronization (HSYNC) signals. An output formatter provides complete support for RGB/YCbCr 4:4:4 and YCbCr 4:2:2, as well as dedicated data clock for easy latching of output data, Moizio said. The device also supports three digitizing channels with individual clamps, an 8-bit programmable gain amplifier, a 3:1 input multiplexer and automatic offset control for both YPbPr and RGB inputs.
Available in both 1.8- and 3.3-V versions, the TVP7001 is sampling now with volume scheduled for December. The TVP7000 is in production today. Both devices are offered in a 100-pin lead-free PZP PowerPad HTQFP package. Evaluation modules are also available.
Pricing for the TVP7000 and TVP7001 is $4.25 and $4.75, respectively, in 1,000-piece quantities. Click here for the TVP7000 data sheet.
