14.10.TEA6415C
14.10.1.General Description
The main function of the IC is to switch 8 video input sources on 6 o utputs. Each output can be
switched on only one of each input. On each input an alignment of the lowest level of the signal is made
(bottom of synch. top for CVBS or black level for RGB signals). Each nominal gain between any input
and output is 6.5dB. For D2MAC or Chroma signal the alignment is switched off by forcing, with an
external resistor bridge, 5 V
Chroma input (with external resistor bridge). All the switching possibilities are changed through the
BUS. Driving 75? load needs an external transistor. It is possible to have the same input connected to
several outputs. The starting configuration upon power on (power supply: 0 to 10V) is undetermined. In
this case, 6 words of 16 bits are necessary to determine one configuration. In other case, 1 word of 16
bits is necessary to determine one configuration.
14.10.2.Features
• 20MHz Bandwidth
• Cascadable with another TEA6415C (Internal address can be changed by pin 7 voltage)
• 8 Inputs (CVBS, RGB, MAC, CHROMA,...)
• 6 Outputs
• Possibility of MAC or chroma signal for each input by switching-off the clamp with an external resistor
bridge
• Bus controlled
• 6.5dB gain between any input and output
• 55dB crosstalk at 5mHz
• Fully ESD protected
