Overview
The THS7353PWR is a low-power, single-supply video buffer fabricated using SiGe BiCom-III technology. It integrates three independent channels with selectable 5th-order Butterworth filters (9-MHz, 16-MHz, 35-MHz) and a bypass mode providing 150-MHz bandwidth. The device operates on a 2.7-V to 5.5-V supply, drawing 16.2 mA total quiescent current. Key features include I2C control, external gain adjustment (0 dB to 14 dB), a 2:1 input MUX, and rail-to-rail output.
Feature Summary
- Integrates selectable 5th-order Butterworth anti-aliasing filters for SDTV, EDTV, and HDTV signal processing.
- Features a 2:1 input multiplexer allowing flexible selection between multiple video sources per channel.
- Provides externally adjustable gain range from 0 dB to 14 dB via dedicated pins for line driving or cable loss compensation.
- Supports AC-coupled (with sync-tip clamp) and DC-coupled input bias modes for versatile system integration.
Applications
- HDTV video buffering for 720p/1080i signals
- Portable USB-powered video devices
- Projector video buffering systems
Procurement Notes
Verify the specific package marking and date code against the manufacturer's latest datasheet revision SLOS484B. Confirm that the ordering suffix 'PWR' corresponds to the TSSOP-20 tape and reel configuration. Ensure compatibility with standard I2C bus voltage levels if interfacing directly with controllers without level shifting.
Selection Notes
Select this component when multi-standard video support is required within a single channel architecture. The integrated filter options eliminate external components for SDTV through HDTV applications. Consider the low power consumption for battery-operated designs and the I2C configurability for dynamic system adjustments.
Part Context
This part belongs to the THS7353 family of video buffers. It is manufactured by Texas Instruments using complementary silicon-germanium technology. The PWR suffix indicates a specific surface-mount packaging variant designed for automated assembly processes in consumer electronics manufacturing.
