Preliminary specification
Single standard multimedia IF-PLL and FM
radio demodulator
TDA9809M
Notes
1.
2.
Video and sound parameters are degraded at V
P
≤
4.5 V.
This parameter is not tested during production and is provided as application information for use in designing the
television receiver.
Loop bandwidth BL = 70 kHz (natural frequency f
n
= 12 kHz; damping factor d
≈
3; calculated for peak level).
Resonance circuit of VCO: Q
0
> 50; C
VCO
= 8.2 pF
±
0.25 pF; C
int
≈
8.5 pF (loop voltage
≈
2.7 V).
Temperature coefficient of external LC circuit is equal to zero.
V
i(VIF)(rms)
= 10 mV;
f = 1 MHz (VCO frequency offset related to picture carrier frequency); white picture
video modulation.
V
i(VIF)
signal for nominal video signal.
The leakage current of the AGC capacitor should not exceed 1
μ
A to avoid larger tilt.
S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 13). B = 5 MHz weighted
in accordance with “CCIR 567”.

The intermodulation figures are defined:
;
α
IM(0.92/1.1)
value at 0.92 or 1.1 MHz referenced to
black/white signal;
;
α
IM(2.76/3.3)
value at 2.76 or 3.3 MHz referenced to colour carrier.
10. Measurements taken with SAW filter G1962 (sound shelf: 20 dB); loop bandwidth = 70 kHz.
a) Modulation VSB; sound carrier

> 0.5 MHz.
b) Sound carrier
on
; SIF SAW filter K9453; f
video
= 10 kHz to 10 MHz.
11. Response speed valid for a VIF input level range of 200
μ
V up to 70 mV.
12. A current source output is provided to match the AFC output signal to different tuning systems. The test circuit is
given in Fig.6 for TV mode and in Fig.11 for radio mode. The AFC steepness can be changed by the resistors at
pin 14.
a) A voltage output is provided to match the AFC output signal to different tuning systems. The DC load current
should not exceed 180
μ
A.
