DESCRIPTION
Fabricated using the Silicon-Germanium (SiGe)
BiCom-III process, the THS7316 is a low power
single-supply 3-V to 5-V, 3-channel integrated video buffer. It incorporates a 5th-order modified
Butterworth filter which is useful as a DAC
reconstruction filter or an ADC anti-aliasing filter. The
36-MHz filter is a perfect choice for HDTV video
which includes Y'P'BP'R 720p/1080i, G'B'R' (R'G'B'),
and VGA/SVGA/XGA signals.
As part of the THS7316 flexibility, the input can be
configured for ac or dc coupled inputs. The DC +
140-mV input offset shift to allow for a full sync
dynamic range at the output with 0-V input. The AC
coupled modes include a transparent sync-tip clamp
option for signals with sync such as Y’ or Green with
sync. AC-coupled biasing for P’B/P’R/Non-sync
channels can be achieved by adding an external
resistor.
The THS7316 is the perfect choice for all output
buffer applications. Its rail-to-rail output stage with
6-dB gain allows for both ac and dc line driving. The
ability to drive 2 video lines per channel, or 75-Ω
loads, allows for maximum flexibility as a video line
driver. The 18.3-mA total quiescent current makes it
an excellent choice for USB powered, portable, or
other power sensitive video applications.
The THS7316 is available in a small SOIC-8 package
that is RoHS compliant.
