4-in-1 Video Decoder With Integrated Audio ADCs Combined With MJPEG
Compression Controller Creates an End-to-End DVR Solution With Improved
Integration, Functionality and Image Quality

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.

Pricing and Availability
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. Please contact a local Techwell sales representative
for evaluation boards, samples and pricing.
