Multistandard VIF-PLL with QSS-IF and
AM demodulator
TDA9810
Notes
1.
2.
Values of video and sound parameters are decreased at V
P
= 4.5 V.
This parameter is not tested during production and is only given as application information for designing the
television receiver.
Loop bandwidth BL = 70 kHz (natural frequency f
n
= 12 kHz; damping factor d
≈
3; calculated for peak level).

Temperature coefficient of external LC-circuit is equal to zero.

f = 1 MHz (VCO frequency offset related to picture carrier frequency); white picture

V
i(IF)
signal for nominal video signal.
Offset current measured between pin 4 and half of supply voltage (V
P
= 2.5 V) under the following conditions: no
input signal at VIF input (pins 1 and 2) and VIF amplifier gain at minimum (V
21
= V
P
). Due to sample-and-hold mode
of the FPLL in L standard, the leakage current of the loop filter capacitor (C = 220 nF) should not exceed 500 nA.
Measurements taken with SAW filter K6257 (sound carrier suppression: 40 dB); loop bandwidth = 70 kHz.
a) Modulation VSB; sound carrier
off
; f
video
> 0.5 MHz.
b) Sound carrier
on
; SIF SAW filter K9453; f
video
= 10 kHz to 10 MHz.
The 7 dB buffer gain accounts for 1 dB loss in the sound trap. Buffer output signal is typically 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 9 to pin 13).
10. 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.
11. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 12). B = 5 MHz weighted
in accordance with “CCIR 567”

12. The intermodulation figures are defined:
;
α
IM(1.1)
value at 1.1 MHz referenced to black/white signal;
;
α
IM(3.3)
value at 3.3 MHz referenced to colour carrier.
13. Response speed valid for a VIF input level range of 200
μ
V up to 70 mV.
14. To match the AFC output signal to different tuning systems a current source output is provided. The test circuit is
given in Fig.8. The AFC-steepness can be changed by the resistors at pin 17.
