PIN DESCRIPTION
Table 1. Pin Description
Pin No
Pin Name
Description
1
PLL2C
Second PLL Loop Filter
2
H-DUTY
DC Control of Horizontal Drive Output Pulse Duty-cycle.
If this pin grounded, the horizontal and vertical outputs are inhibited. By connecting a
capacitor on the 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
NC
7
NC
8
NC
9
NC
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 freqency
change detected on pin 13. 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.
15
H-POS
DC Control for Horizontal Centering
16
XRAY-IN
X-RAY Protection input (with Internal latch function)
17
H-SYNC
TTL Horizontal Sync Input
18
Vcc
Supply Voltage (12V Typical)
19
GND
Ground
20
H-OUTEM
Horizontal Drive Output (emiter of internal transistor)
21
H-OUTCOL
Horizontal Drive Output (open collector of internal transistor)
22
B+OUT
B+ PWM Regulator output
23
SBLK
OUT
Safety Blanking output. Activated during frequency changes, when X-RAY input is
triggered or when VS is too low.
24
VGND
Vertical Section Signal Ground
25
VAGCCAP
Memory Capacitor for Automatic Gain Control Loop in Vertical Ramp Generator
26
V
REF
Vertical Section Reference Voltage
