Description

The TSH103 is a low cost video buffer. It is

dedicated to drive video signals from any video

DACs output on 75

Ω video lines in standard

definition. With a real benefit in terms of

integration and cost saving, this product is

particularly efficient for the replacement of current

discrete solutions using transistors, coil and

capacitors for buffering and filtering.

This triple channel is designed to drive either

CVBS/Y-C or RGB or YPbPr or YUV formats.

Each channel features an internal 6MHz

reconstruction filter and a 6dB buffer (attenuation

of 27MHz sampling and good output impedance

matching with the video line).

The TSH103 requires a single 5V power supply. It

is available in SO-8 plastic package.
