Multistandard VIF-PLL with QSS-IF
and dual FM-PLL/AM demodulator
TDA9814T
Notes to the characteristics
1.
Values of video and sound parameters are decreased at V
P
= 4.5 V.
2.
This parameter is not tested during production and is only given as application information for designing the
television receiver.
3.
Loop bandwidth BL = 75 kHz (natural frequency f
n
= 11 kHz; damping factor d
≈
3.5; calculated with sync level within
gain control range). Resonance circuit of VCO: Q
0
> 50; C
ext
= 8.2 pF
±
0.25 pF; C
int
≈
8.5 pF (loop voltage
approximately 2.7 V).
4.
Temperature coefficient of external LC-circuit is equal to zero.
5.
V
i IF
= 10 mV RMS;
f = 1 MHz (VCO frequency offset related to picture carrier frequency); white picture
video modulation.
6.
V
i IF
signal for nominal video signal.
7.
Measurements taken with SAW filter G3962 (sound carrier suppression: 40 dB); loop bandwidth BL = 75 kHz:
a) Modulation VSB; sound carrier
off
; f
video
> 0.5 MHz.
b) Sound carrier
on
; SIF SAW filter L9453; f
video
= 10 kHz to 10 MHz.
8.
The 7 dB buffer gain accounts for 1 dB loss in the sound trap. Buffer output signal is typical 2 V (p-p), in event of
CVBS video amplifier output typical 1 V (p-p). If no sound trap is applied a 330
resistor must be connected from
output to input (from pin 18 to pin 19).
9.
The leakage current of the AGC capacitor should not exceed 1
μ
A at B/G standard respectively 10 nA current at
L standard. Larger currents will increase the tilt.
10. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 8). B = 5 MHz weighted
in accordance with “CCIR 567”
11. The intermodulation figures are defined:
V
at 4.4 MHz
V
0
at 1.1 MHz
V
at 4.4 MHz
0
at 3.3 MHz
; α
1.1
value at 1.1 MHz referenced to black/white signal;
3.6dB
; α
3.3
value at 3.3 MHz referenced to colour carrier.
12. Response speed valid for a VIF input level range of 200
μ
V up to 70 mV.
13. To match the AFC output signal to different tuning systems a current source output is provided. The test circuit is
given in Fig.7. The AFC-steepness can be changed by the resistors at pin 20.
14. Depending on the ratio
C/C
0
of the LC resonant circuit of VCO (Q

15. Source impedance: 2.3 k
in parallel to 12 pF (SAW filter); f

= 38.9 MHz.
