CIRCUIT DESCRIPTION
The main functions of the I.C. are following :
Video Switching
2 electronically switched inputs :
- one 2.5VPPinput for internal video.
- one 1VPPinput for signal coming from the peri-TV plug.
2 outputs :
-1VPPoutput (low impedance 75) for peri-TV plug.
-1VPPoutput low impedance for video section of the TV set.
Each input and output is protected from ground short-circuit. The 75output is protected through a75Ωresistor.
Audio Switching
Two electronically switched inputs :
- 300mV rms input coming from internal audio.
- 100mV rms input coming from the peri-TV plug one low impedance output 300mV
RMS
.
Inputs and outputs are also protected against ground short-circuit.
Switching Logic
The logic takes into account the informations on 3 pins.
- Internal or external video and sound (pin 8 peri TV plug)
- Band III information
- Video recorder key.
External Video and Audio signals are selected in two cases.
- When there is a voltage information coming from peri-TV plug.
- When the video recorder key is selected (on TV front panel) and programmed on band III.
This I.C. includes aninternal switch (open collector transistor) which commutes the time constant of the horizontal PLL circuit in case of video recorder reception.

SAFETY INFORMATION FOR CRITICAL APPLICATIONS
Voltage on pin 9 must not exceed the VCCvoltage on pin 13. In case of risk of over voltage, use the protection as described in Figure 2. All connections toPeritelplugareterminated by low
impedance loads(75W), excepttheexternalsound input. In case of risk of electrostatic discharge, use the protection as described in Figure 3.
