THS7315 - Texas Instruments

THS7315 3-Channel SDTV Video Amplifier

Fabricated using the revolutionary complementary silicon-sermanium (SiGe) BiCom3 process, the THS7315 is a low-power, single-supply, 3-V to 5-V 3-channel integrated video buffer. It incorporates a 5th-order Butterworth filter that is useful as a digital-to-analog converter (DAC) reconstruction filter or an analog-to-digital converter (ADC) anti-aliasing filt.

Features

• Three SDTV Video Amplifiers for CVBS, S-Video, Y'P'BP'R 480i/576i, Y'U'V', or G'B'R' (R'G'B')
• Integrated Low-Pass Filters:
  – 5th-Order, 8.5-MHz (
  –3dB) Butterworth
  –
  –1dB Passband Bandwidth at 7 MHz
  – 47 dB Attenuation at 27 MHz
• Versatile Input Biasing:
  – DC-Coupled with 230-mV Output Shift
  – AC-Coupled with Sync-Tip Clamp
  – Allows AC-Coupled With DC-Biasing
• Built-in 5.2 V/V Gain (14.3 dB)
• +3-V to +5-V Single Supply Operation
• Rail-to-Rail Output:
  – Output Swings Within 100 mV of the Rails, Allowing AC- or DC-Output Coupling
  – Supports Driving Two Lines per Channel
