PIN DESCRIPTION
Pin
Name
Function
1
V-FOCUS
Vertical Dynamic Focus Output
2
H-LOCKOUT
First PLL Lock/Unlock Output
3
PLL2C
Second PLL Loop Filter
4
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.
5
H-FLY
Horizontal Flyback Input (positive polarity)
6
H-GND
Horizontal Section Ground
7
H-REF
Horizontal Section Reference Voltage, must be filtered
8
FC2
VCO Low Threshold Filtering Capacitor
9
FC1
VCO High Threshold Filtering Capacitor
10
C0
Horizontal Oscillator Capacitor
11
R0
Horizontal Oscillator Resistor
12
PLL1F
First PLL Loop Filter
13
H-LOCKCAP
First PLL Lock/Unlock Time Constant Capacitor. 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.
14
PLL1INHIB
TTL-Compatible Input for PLL1 Output Current Inhibition
15
H-POS
DC Control for Horizontal Centering
16
XRAY-IN
X-RAY protection Input (with internal latch function)
17
H-SYNC
TTL compatible Horizontal Sync Input
18
VCC
Supply Voltage (12V Typ.)
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
BLK OUT
Blanking Output, activated during frequency changes, when X-RAY Input is triggered, when
VS is too low, or when Device is in stand-by mode (through H-DUTY Pin 2) and during H-FLY,
V-FLY, V-SYNC, VSawth retrace.
23
CORNER
DC Control of Corner Correction Amplitude
24
V-GND
Vertical Section Signal Ground
25
V-AGCCAP
Memory Capacitor for Automatic Gain Control Loop in Vertical Ramp Generator
26
V-REF

29
C-CORR
DC Control of Vertical C-Correction
30
V-OUT
Vertical Ramp Output (with frequency independant amplitude and S-Correction)
31
V-AMP
DC Control of Vertical Amplitude Adjustment
32
VDCOUT
Vertical Position Reference Voltage Output
33
V-POS
DC Control of Vertical Position Adjustment
34
V-SYNC
TTL-Compatible Vertical Sync Input
35
VDCIN
Geometric Correction Reference Voltage Input
36
V-FLY
Vertical Flyback Input (positive polarity)
37
EWOUT
East /West Pincushion Correction Parabola Output
38
KEYST
DC Control of Keystone Correction
39
EWAMP
DC Control East/West Pincushion Correction Amplitude
40
GEOMOUT
Side Pin Balance & Parallelogram Correction Parabola Output
41
KEYBAL
DC Control of Parallelogram Correction
42
SPINBAL
DC Control of Side Pin Correction Amplitude
TDA9105A
2/31
