Description
The TSH103 is a low cost video buffer. It is
dedicated to drive video signals from any video
DACs output on 75Ω 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.
