FEATURES
DESCRIPTION
2
4-SDTV Video Amplifiers for CVBS, S-Video,
Fabricated using the revolutionary complementary
Y'P'BP'R 480i/576i, Y'U'V', or G'B'R' (R'G'B')
Silicon-Germanium (SiGe) BiCom3X process, the
THS7374 is a low-power, single-supply 3 V to 5 V
Integrated Low-Pass Filters:
four-channel integrated video buffer. It incorporates a
–
6th-Order 9.5-MHz (–3 dB) Butterworth
sixth-order Butterworth filter (able to be bypassed)
–
–1 dB Passband Bandwidth at 8.2-MHz
which is useful as a digital-to-analog converter (DAC)
reconstruction filter or an analog-to-digital converter
–
54-dB Attenuation at 27-MHz
(ADC) anti-aliasing filter. The 9.5-MHz filter is a
150-MHz (–3 dB) Filter Bypass Mode
perfect
choice
for
SDTV
video
that
includes
Versatile Input Biasing
composite (CVBS), s-video, Y'U'V', G'B'R' (R'G'B'),
and Y'P'BP'R 480i/576i.
–
DC-Coupled with 300-mV Output Shift
–
AC-Coupled with Sync-Tip Clamp
As part of the THS7374 flexibility, the input can be
configured for either ac or dc-coupled inputs. The
–
AC-Coupled with Biasing Allowed
300-mV output level shift allows for a full sync
Built-in 6-dB Gain (2 V/V)
dynamic range at the output with 0-V input. The
+3-V to +5-V Single-Supply Operation
ac-coupled modes include a transparent sync-tip
clamp option for CVBS, Y', and G'B'R' signals with
Rail-to-Rail Output:
sync. AC-coupled biasing for C'/P'B/P'R channels can
–
Output Swings Within 100 mV from the
easily be achieved by adding an external resistor.
Rails to Allow AC or DC Output Coupling
The THS7374 is the perfect choice for all video buffer
–
Supports Driving 2 Lines per Channel
applications. Its rail-to-rail output stage with 6-dB gain
Low 9.6-mA at 3.3-V Total Quiescent Current
allows for both ac and dc line driving. The ability to
0.1-mA Disabled Supply Current Function
drive two lines per channel, or 75-
loads, allows for
maximum flexibility as a video line driver. The 9.6-mA
Low Differential Gain/Phase of 0.15%/0.3°
total quiescent current at 3.3 V and 0.1-mA disabled
Lead-Free and Green TSSOP-14 Package
current makes it an excellent choice for portable or
other power-sensitive applications.
APPLICATIONS
The THS7374 is available in a TSSOP-14 package
Low-Cost SCART Systems
that is lead-free and green (RoHS) compliant.
