SAN JOSE, Calif. - Techwell, Inc., a designer of mixed signal video semiconductor solutions for the consumer, security surveillance, and automotive markets, today introduced three additions to its line of integrated circuits for security surveillance applications. Extending Techwell’s TW2800 family of security ICs, the pin-to-pin compatible TW2815 and TW2816 four channel video decoders convert analog composite video signals to digital component YCbCR data for standalone and PC-based DVR security applications. The TW2815 also includes audio codecs and combined with the new TW2700 4-Channel Compression Controller provide a scalable, end-to-end MJPEG DVR solution. Techwell will be demonstrating these three new semiconductors for the security surveillance market at the ISC West Show held in Las Vegas NV April 5-7, 2006 Booth# 4127.
The TW2815 and TW2816 include four integrated analog anti-aliasing filters, 10-bit CMOS ADCs, and high-performance adaptive 4H comb filters for all NTSC/PAL standards. Both ICs provide simultaneous four channel Full D1 and CIF time-multiplexed outputs with 54MHz, and both operate at an ultra low level of power (typically 480-500 mW). In addition, the TW2815 offers four integrated audio ADCs, an audio DAC, multi-channel audio mixed analog output, and support for a standard I2S interface for record output and playback input.
The TW2700 is a real-time 4-channel video compression controller for security applications that can compress and decompress 4 full-size video data streams simultaneously. As Techwell’s first chip in the CODEC segment of the DVR application, this RISC-based controller can be used with the TW2815 to provide a complete DVR solution. Features include four ITU-R BT.656 compatible video input ports; an independent compression engine for each channel with a proprietary algorithm; support for Triplex operations, simultaneous recording, playback and network connection; and support for up to sixteen channels through cascade mode.
“These products represent Techwell’s continued commitment to the security surveillance market.†said David Nam, Techwell’s Vice President of Sales and Marketing.
The pin-to-pin compatible TW2815 and TW2816 use a 100-pin TQFP package, are currently sampling, and will go mass production in Q2 2006. The TW2700 uses a 256-pin PQFP package, will began sampling in Q2 2006, and will go mass production in Q3 2006.
