... Set-top boxes ■ DVD players/recorders Description The TSH103 is a low-cost video buffer 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 ...
