DC Shifter

Description

The TSH346 is a triple single-supply video buffer

featuring an internal gain of 6 dB and a 36 MHz

filtering for HD video outputs on 75-Ω video lines.

The TSH346 is ideal to drive either YUV, YPbPr or

RGB signals from video DAC outputs. The main

advantage of this circuit is that its input DC level

shifter allows for video signals on 75-Ωvideo lines

without damaging the synchronization tip of the

video signal, and with no input capacitor, while

using a single 5 V power supply. The DC level

shifter is internally fixed and optimized to keep the

output video signals between low and high output

rails. This level is as low as possible to minimize

the output DC level in the video line.

The TSH346 is available in an SO-8 plastic

package for optimum space saving.
