Techwell faces and monitors the market and pushes away in three sections of integrated circuit newly safely
Composite signal the intersection of video and semiconductor solve conceptual design trader Techwell push away newly a few days ago 3 style use for, monitor the intersection of integrated circuit and product of field safely. The stitch totally compatible TW2815 and TW2816 four -channel video decoder has expanded TW2800 serial safe integrated circuit of Techwell, they turn the analog composite video signal into the digital structural YCbCR data to use for setting up only and digital camera (DVR) based on PC Safe application. TW2815 also includes the coder-decoder of the audio frequency, and there are new TW2700 four channel compression control devices (4 - Channel Compression Controller) In order to can offer staging is carried to the end MJPEG DVR solution. The 5th such as April at 2006 such as Techwell - 7 reach state demonstrate whether there are at Ann on these three sections of productses semi-conductives newses at the exhibitions ISC West Show where the Las Vegases holds China at Chinas American Monitor the application of the market field completely, the number of station of the exhibition is 4127.
TW2815, TW2816 including four Integrated simulation resist the sawtooth distortedly (anti-aliasing) Electric-wave filter, 10 CMOS analog-to-digital converter units, and accord with all NTSC/PAL canonial high performance adapting to 4H comb filter. Two integrated circuit these offer 54MHz four the intersection of letter and dishes of Full D1 and the intersection of CIF and the intersection of time and plural output that move ahead simultaneously, and consumption of the two is all extremely low (usually 480-500mW) . In addition, TW2815 offers four Integrated audio frequency analog-to-digital converter unit, a digital analog converter, multi channel audio frequency to mix the analog output, and support the standard I2S interface to be for recording and producing and exporting and returning input.
TW2700 is a real-time four -channel video compression control device, used in the safe application, it can compress and decompress four canonial video data flows at the same time. As first coder-decoder chips used for video recorder of the digital video of Techwell, this control device based on RIS framework can use with TW2815 in order to offer a kind of complete digital video video recorder solution together. Its characteristic includes the video input port of four compatible ITU-R BT.656s, each signal channel has one independent and adopting the exclusive algorithmic compressed engine, supporting Triplex operation, records and produces synchronously, returns and network link, and pass cascade (cascade) The mode supports up to 16 signal channels.
Techwell marketing executive vice president David Nam shows: "Product these have reflected Techwell is devoted to monitoring the efforts of the market safely constantly. "
The complete stitch compatible TW2815 and TW2816 adopts a kind of 100 stitches of TQFPs to capsulate, is producing stage in the sample at present, and would begin batch productino in the second quarter of 2006. TW2700 adopts a kind of 256 stitches of PQFPs to capsulate, would begin to produce samples in the second quarter of 2006, and would begin batch productino in the third quarter of 2006.
