Description
The TSH103 is a low-cost video buffer. It is
dedicated to drive video signals from any video
DAC 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 6 MHz
reconstruction filter and a 6 dB buffer (attenuation
of 27 MHz sampling and good output impedance
matching with the video line).
The TSH103 requires a single 5 V power supply.
It is available in an SO-8 plastic package.
