CIRCUIT DESCRIPTION The main functions of the I.C. are following : Video Switching 2 electronically switched inputs : - one 2.5VPP input for internal video. - one 1VPP input for signal coming from the peri-TV plug. 2 outputs : - 1VPP output (low impedance 75) for peri-TV plug. - 1VPP output low impedance for video section of the TV set. Each input and output is protected from ground short-circuit. The 75 output is protected through a 75 resistor. 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 300mVRMS. APPLICATION CIRCUIT 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 an internal 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 VCC voltage on pin 13. In case of risk of over voltage, use the protection as described in Figure 2. All connections to Peritel plug are terminated by low impedance loads (75W), except the external sound input. In case of risk of electrostatic discharge, use the protection as described in Figure 3.
