General Description
The TDA 6920 switches 7 video input sources to 5 outputs. Each output can be switched to only one input, but one input can be switched to all outputs. The C-input may be combined with one CVBS input as Y for Y+C (S-VHS) operation. Y+C operation is selected by bus.

FEATUREs
■ Fast I2C-BUS controlled (max. 400 kHz)
■ Cascadable (2 bus addresses)
■ 7 CVBS inputs, 5 outputs 3 inputs with clamp disable by bus
■ 1 input selectable as Y-input (S-VHS)
■ 1 additional C-input (S-VHS)
■ Y+C operation for S-VHS selected by bus
■ Fully ESD protected
■ -60 dB max. crosstalk at 5 MHz (P-DSO-28 only)
■ Low operating voltage of 7.5 V
■ 5V operation is possible with reduced output signals of max. 2 Vpp
■ 15 MHz minimum bandwidth
■ Noise insensitive clamping inputs
■ low impedance off condition separate for each output

APPLICATION
■ Television sets
■ Satellite receivers
■ Video mixing desks
