TI Introduces Industry's First Triple Video Amplifier with Integrated Filters and HV Sync Capability

TI Introduces Industry's First Triple Video Amplifier with Integrated Filters and HV Sync Capability

October 25, 2006

High Integration Simplifies Design, Saves Board Space and System Cost

    DALLAS, Oct. 25 /Xinhua-PRNewswire/ -- Texas
Instruments Incorporated (TI) (NYSE: TXN) today introduced
the first video amplifier with integrated filters that is
capable of handling both analog RGB signals and digital
horizontal and vertical (HV) sync signals on a single chip.
The new device saves up to 80 percent board space when
compared to traditional amplifier solutions for video
projectors, professional video, broadcast video, computer
display, traditonal and digital TV systems. In addition,
designers benefit from improved performance and maximum
flexibility via I2C programmability of all functions. (

    The THS7327 integrates three analog video channels and
two digital channels for HV sync, greatly simplifying
systems design and reducing component count.  The three
analog channels incorporate unity gain buffering and
monitor feed-through paths to handle all standard video
formats, including RGB, YPbPr and CVBS. Designers gain
flexibility with the amplifier's I2C-programmable functions
including: integrated two-to-one input multiplexers to
enable switching of multiple video sources; fifth-order
antialiasing filters to enable use with multiple video
standards;  and input bias modes including DC, DC plus
level shift, AC and AC sync tip clamp to enable interfacing
to multiple video sources.

    The programmable filters and input bias modes provide
all the common analog signal conditioning requirements for
implementation of the following standards, while
eliminating the need for more than 20 external components: 
 

    -- 9-MHz filter for SDTV video including CVBS, S-Video
and 480i/576i;

    -- 16-MHz filter for EDTV 480p/576p and VGA signals; 

    -- 35-MHz filter for HDTV 720p/1080i and SVGA signals;


    -- 75-MHz filter for HDTV 1080p and XGA/SXGA signals; 

    -- For UXGA/QXGA RGB signals, the filters can be
bypassed to provide 
       500-MHz bandwidth and 1150-V/¦Ìs slew rate
amplifiers to buffer the
       signals.

    Each analog channel with an integrated programmable
filter provides a unity gain buffer for input into a video
decoder or video analog-to-digital converter (ADC) and a
separate path without a filter for monitor pass-through.
The monitor pass-through includes a 6-dB gain output buffer
with SAG correction capability, bandwidth of 500 MHz and
slew rate of 1300 V/ ¦Ìs.  Manufactured in TI's proprietary
BiCom3 complementary bipolar silicon germanium process, the
THS7327 offers 2.7-V to 5-V single-supply operation, which
results in power savings of up to 50 percent by eliminating
the negative supply required by traditional designs.  

    The THS7327 device joins TI's extensive offering of
high-performance analog and digital signal processor (DSP)
products for video applications, including DaVinci(TM)
processors optimized for digital video systems, the
TVP7000/1 triple 8/10-bit video ADC, and DLP(R) technology.
TI provides the silicon, software, systems expertise and
support for customers' video designs, enabling them to
accelerate market entry. For more information on TI's video
