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

● Video mixing desks
