Description

Data input (no pull down - capability)

Data input and output (pull down - capability for acknowledge

and data reply)

Vertical Synchronization Signal from STV2118A

Output for controlling the ext. series regulator transistor

Supply voltage of scanning part, connected with external series

regulator transistor

Loop filter for horizontal 2 x FLINE VCO

Regulation of vertical saw tooth amplitude

Ground

Input voltage = 1 to 7.8V = vertical size compensation

Voltage input for horizontal flyback, polarity positive

Oversize blanking output :

- open collector output : high ohmic = blanking

- low (transistor saturated) = no blanking

Input of the error amplifier for the East-West modulator

Output of the error amplifier for the East-West modulator

(current output, biasing directly the darlington output transistor)

Output of transconductance amplifier, pin has to be connected

to the inverting input of the vertical power amplifier

Input of internal resistor bridge for sensing the vertical

deflection YOKE current
