Product speciï¬cation
TDA8540
FEATURES
• I2C-bus or non-I2C-bus mode (controlled by
DC voltages)
• S-VHS or CVBS processing
• 3-state switches for all channels
• Selectable gain for the video channels
• sub-address facility
• Slave receiver in the I2C mode
• Auxiliary logic outputs for audio switching
• System expansion possible up to 7 devices
(28 sources)
• Static short-circuit proof outputs
• ESD protection.
GENERAL DESCRIPTION
The TDA8540 has been designed for switching between
composite video signals, therefore the minimum of four
input lines are provided as requested for switching
between two S-VHS sources. Each of the four outputs can
be set to a high impedance state, to enable parallel
connection of several devices.
APPLICATIONS
• Colour Television (CTV) receivers
• Peritelevision sets
• Satellite receivers.
