1.1
Type
TDA 6920
TDA 6920X
1.2
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.

Semiconductor Group
Fast I
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
