Name

Function

1

PLL2C

Second PLL Loop Filter

2

H-DUTY

DC Control of Horizontal Drive Output Pulse Duty-cycle.

If this pin is grounded, the horizontal and vertical outputs are inhibited. By connecting a

capacitor on this pin a soft-start function may be realized on h-drive output.

3

H-FLY

Horizontal Flyback Input (positive Polarity)

4

H-GND

Horizontal Section Ground. Must be connected only to components related to H blocks.

5

H-REF

Horizontal Section Reference Voltage. Must be filtered by capacitor to Pin 4

6

S4

Hor S-CAP Switching

7

S3

Hor S-CAP Switching

8

S2

Hor S-CAP Switching

9

S1

Hor S-CAP Switching

10

C0

Horizontal Oscillator Capacitor. To be connected to Pin 4.

11

R0

Horizontal Oscillator Resistor. To be connected to Pin 4.

12

PLL1F

First PLL Loop Filter. To be connected to Pin 4.

13

HLOCK-CAP

First PLL Lock/Unlock Time Constant Capacitor. Capacitor filtering the frequency change

detected on Pin13. When frequency is changing, a blanking pulse is generated on Pin 23, the

duration of this pulse is proportionnal to the capacitor on Pin 13. To be connected to Pin 4.

14

FH-MIN

DC Control for Free Running Frequency Setting. Comming from DAC output or DC voltage

generated by a resistor bridge connected between Pin 5 and 4.
