FEATURES
DESCRIPTION
2345
Three SDTV Video Amplifiers for CVBS,
Fabricated using the revolutionary, complementary
S-Video, Y’/P’B/P’R, 480i/576i, Y’U’V’, or G'B'R'
Silicon-Germanium (SiGe) BiCom3X process, the
THS7364 is a low-power, single-supply, 2.7-V to 5-V,
Three Full-HD Selectable Filters for Y’/P’B/P’R,
six-channel integrated video buffer. It incorporates
G’B’R’, or Computer RGB
three SDTV filters and three Full-HD (also known as
Bypassable Sixth-Order Low-Pass Filters:
True-HD) HDTV filters. All filters feature bypassable
–
Fixed SD Channels: 9.5-MHz
sixth-order Butterworth characteristics that are useful
as digital-to-analog converter (DAC) reconstruction
–
Fixed Full-HD Channels: 72-MHz
filters
or
as
analog-to-digital
converter
(ADC)
Versatile Input Biasing:
anti-aliasing filters.
–
DC-Coupled with 300-mV Output Shift
The THS7364 has flexible input coupling capabilities,
–
AC-Coupled with Sync-Tip Clamp or Bias
and can be configured for either ac- or dc-coupled
Built-in 6-dB Gain (2 V/V)
inputs. The 300-mV output level shift allows for a full
sync dynamic range at the output with 0-V input.
+2.7-V to +5-V Single-Supply Operation
AC-coupled modes include a transparent sync-tip
Rail-to-Rail Output:
clamp for CVBS, Y', and G'B'R' signals. AC-coupled
–
Output Swings within 100 mV from the
biasing for C'/P'B/P'R channels can easily be achieved
Rails: Allows AC or DC Output Coupling
by adding an external resistor to VS+.
–
Supports Driving Two Video Lines/Channel
The THS7364 is an ideal choice for a wide range of
Low Total Quiescent Current: 23.4 mA at 3.3 V
video buffer applications. Its rail-to-rail output stage
with 6-dB gain allows for both ac and dc line driving.
Disabled Supply Current Function: 0.1 mA
The ability to drive two lines, or 75-
loads, allows for
Low Differential Gain/Phase: 0.25%/0.4°
maximum flexibility as a video line driver. The
23.4-mA total quiescent current at 3.3 V and 0.1 mA
APPLICATIONS
(disabled mode) makes it well-suited for systems that
Set Top Box Output Video Buffering
must meet power-sensitive Energy Star standards.
PVR/DVDR Output Buffering
The THS7364 is available in a TSSOP-20 package
BluRay Output Video Buffer
that is lead-free and green (RoHS-compliant).
