FEATURES

DESCRIPTION

2345

• Three SDTV Video Amplifiers for CVBS,

Fabricated using the revolutionary, complementary

Silicon-Germanium (SiGe) BiCom3X process, the

THS7364 is a low-power, single-supply, 2.7-V to 5-V,

•

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

Rails: Allows AC or DC Output Coupling

–

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-

Ω 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

•

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).
