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-28-1 only)
● Low operating voltage of 7.5 V
● 5 V 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
