3-Channel SDTV Video Amplifier with 5th-Order Filters and 5.2-V/V Gain
Three SDTV Video Amplifiers for CVBS,
Fabricated using the revolutionary complementary

THS7315 is a low-power, single-supply, 3-V to 5-V
3-channel integrated video buffer. It incorporates a
Integrated Low-Pass Filters:
5th-order Butterworth filter that is useful as a
–
5th-Order, 8.5-MHz (–3dB) Butterworth
digital-to-analog converter (DAC) reconstruction filter
–
–1dB Passband Bandwidth at 7 MHz
or an analog-to-digital converter (ADC) anti-aliasing
filter. The 8.5-MHz filter is a perfect choice for SDTV

DC-Coupled with 230-mV Output Shift
Y’P’BP’R 480i/576i.
–
AC-Coupled with Sync-Tip Clamp
The THS7315 inputs can be either ac- or dc-coupled.
–
Allows AC-Coupled With DC-Biasing
The 230-mV output level shift allows for a full sync
dynamic range at the output with 0 V input. The
Built-in 5.2 V/V Gain (14.3 dB)
ac-coupled modes include a transparent sync-tip
+3-V to +5-V Single Supply Operation
clamp option for CVBS, Y', and G'B'R' signals with
Rail-to-Rail Output:
bottom-level sync. AC-coupled biasing for C'/P'B/P'R
channels can easily be achieved by adding an
–
Output Swings Within 100 mV of the Rails,
external resistor to VS+.
Allowing AC- or DC-Output Coupling
–
Supports Driving Two Lines per Channel
The THS7315 is the perfect choice for all output
buffer applications. Its rail-to-rail output stage with
Low Total Quiescent Current: 15.6 mA at 3.3 V
5.2-V/V gain allows for both ac and dc line driving,
Low Differential Gain/Phase of 0.2%/0.3°
making it a perfect choice for DaVinci processors.
Lead-free, Green SOIC-8 Package
The ability for each channel to drive two video lines,
or 75-
loading, allows for maximum flexibility as a
video line driver. The 15.6-mA quiescent current at
3.3 V also makes it an excellent choice for
Set Top Box Output Video Buffering
USB-powered, portable, or other power-sensitive
PVR/DVDR Output Buffering
video applications
USB/Portable Low-Power Video Buffering
The THS7315 is available in a small SOIC-8
package that is lead-free and compliant with green
requirements.
3.3-V Single-Supply DC-Input/DC-Output Coupled Video Line Driver
