Product speciﬁcation

Alignment-free multistandard vision and

FM sound IF-PLL demodulator

TDA9880

Notes

1. Values of video and sound parameters can be decreased at VP = 4.5 V.

2. The sound carrier frequencies (depending on TV standard) are attenuated by the integrated sound carrier traps

(see Figs 13 to 18);

H (s) is the absolute value of transfer function.

3. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 13). B = 4.2 MHz

(M/N standard) or B = 5.0 MHz (B/G, I and D/K standard) weighted in accordance with

“CCIR 567”.

4. The intercarrier output signal at pin 11 can be calculated by the following formula taking into account the internal

video signal with 1.1 V (p-p) as a reference:

where:

= correction term for RMS value,

= sound-to-picture carrier ratio at VIF input (pins 1 and 2) in dB,

6 dB = correction term of internal circuitry and

±3 dB = tolerance of video output and intercarrier output amplitude
