I2C-bus controlled single and multistandard
alignment-free IF-PLL demodulators
TDA9885; TDA9886
9. Measurements taken with SAW filter M1963M (sound shelf: 20 dB); loop bandwidth BL = 70 kHz.
a) Modulation Vestigial Side-Band (VSB); sound carrier off; fvideo > 0.5 MHz.
b) Sound carrier on; fvideo = 10 kHz to 10 MHz.
10. AC load; CL < 20 pF and RL >1k. 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).
11. The sound carrier trap can be bypassed by switching the I2C-bus. In this way the full composite video spectrum
appears at pin CVBS. The amplitude is 1.1 V (p-p).
12. If selected by the I2C-bus, the VIF-AGC voltage can be monitored at pin OP2, and pin OP1 can be used as input. In
this case, both pins cannot be used for the normal port function.
13. The response time is valid for a VIF input level range from 200
Vto70mV.
14. To match the AFC output signal to different tuning systems a current source output is provided. The test circuit is
given in Fig.10. The AFC slope (voltage per frequency) can be changed by resistors R1 and R2.
15. The tolerance of the reference frequency determines the accuracy of the VIF-AFC, FM demodulator centre
frequency and maximum FM deviation.
16. The intercarrier output signal at pin SIOMAD can be calculated by the following formula taking into account the
internal video signal with 1.1 V (p-p) as a reference:
V
and
where:
is the correction term for RMS value,
is the sound-to-picture carrier ratio at pins VIF1 and VIF2
in dB, 6 dB is the correction term of internal circuitry and
±3 dB is the tolerance of video output and intercarrier output
Vo(intc)(rms).
17. For normal operation (with the I2C-bus) no DC load at pin SIOMAD is allowed. The second module address (MAD2)
will be activated by the application of a 2.2 k
resistor between pin SIOMAD and ground. If this MAD2 is activated,
also the power-on set-up state activates a VIF frequency of 58.75 MHz.
18. SIF input level is 10 mV (RMS); VIF input level is 10 mV (RMS) unmodulated.
19. Measured with an FM deviation of 25 kHz and the typical AF output voltage of 500 mV (RMS). The AF output signal
can be attenuated by 6 dB to 250 mV (RMS) via the I2C-bus. For handling a frequency deviation of more than 55 kHz,
the AF output signal has to be reduced in order to avoid clipping (THD < 1.5 %).
20. The lower limit of the audio bandwidth depends on the value of the capacitor at pin AFD. A value of CAF = 470 nF
leads to fAF(3dB) ≈ 20 Hz and CAF = 220 nF leads to fAF(3dB) ≈ 40 Hz.
21. For all S/N measurements the VIF modulator in use has to meet the following specifications:
a) Incidental phase modulation for black-to-white jump less than 0.5 degrees.
b) QSS AF performance, measured with the television demodulator AMF2 (audio output, weighted S/N ratio) better
than 60 dB (at deviation 27 kHz) for 6 kHz sine wave black-to-white video modulation.
c) Picture-to-sound carrier ratio PC/SC1 = 13 dB (transmitter).
