TEA6415C:
General Description:
The main function of the TEA6415C is to switch 8 video input sources on the 6 outputs.
Each output can be switched to only one of the inputs whereas but any same input may be connected to several outputs.
All switching possibilities are controlled through the lyC-bus.
Features:
20 MHz Bandwith
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 switehing-off the clamp with an external resistor bridge
Bus controlled
6.5dB gain between any input and output
-55dB crosstaljk at 5MHz
Fully ESD protected

TDA9830:
General description:
The TDA9830, a monolithic integrated circuit, is designed for AM-sound demodulation used in L- and L'-standard.
The 1C provides an audio source selector and also mute switch.
Features:
• Adjustment free wideband synchronous AM demodulator
• Audio source-mute switch (low noise)
• Audio level according EN50049
• 5 to 8V power supply or 12 V alternative
• Low power consumption
