TSH103IDT

Overview

The TSH103IDT is a low-cost triple video buffer and filter designed for standard definition applications. It integrates three channels, each featuring an internal 6 MHz fourth-order reconstruction filter and a 6 dB gain buffer optimized for driving 75 Ω video lines. The device operates on a single 5 V supply (4.5 to 5.5 V range) and supports CVBS/Y-C, RGB, YPbPr, or YUV formats. Key electrical characteristics include a typical supply current of 7.1 mA per channel, a -1 dB bandwidth of 7.4 MHz, and a differential gain/phase of 0.5%. It is housed in an SO-8 plastic package.

Feature Summary

• Integrates three independent channels with built-in 6 MHz reconstruction filters
• Provides 6 dB voltage gain buffering specifically matched for 75 Ω transmission lines
• Operates from a single 5 V power supply with output DC shift capability
• Supports multiple standard definition video signal formats including RGB and YPbPr

Applications

• Standard definition televisions
• Set-top boxes
• DVD players and recorders

Procurement Notes

Verify the specific ordering suffix against official STMicroelectronics documentation to confirm the packing method. The IDT suffix indicates tape and reel packaging, whereas the ID suffix denotes tube packaging. Ensure the temperature grade matches the application requirements before procurement.

Selection Notes

Select this component when replacing discrete transistor, coil, and capacitor solutions for video buffering and filtering. It is suitable for designs requiring integration of reconstruction filtering and impedance matching within a compact surface-mount footprint. Verify that the system operates within the specified 4.5 V to 5.5 V supply range.

Part Context

The TSH103 belongs to a family of low-cost video buffers manufactured by STMicroelectronics. It is engineered to simplify the design of standard definition video signal paths by combining buffering, filtering, and impedance matching functions into a single integrated circuit, thereby reducing component count and board space.
