22. Calculation of the loop filter parameters can be done approximately using the following formulae:
The formulae are only valid under the following conditions:
≤ 1 and C
S >5CP
where:
KO is the VCO steepness
or
;
KD is the phase detector steepness
;
R is the loop resistor;
CS is the series capacitor;
CP is the parallel capacitor;
fo is the natural frequency of PLL;
BL3dB is the loop bandwidth for 3 dB;
is the damping factor. For examples, see Table 19.
23. The PC/SC ratio is calculated as the addition of TV transmitter PC/SC1 ratio and SAW filter PC/SC1 ratio. This PC/SC
ratio is necessary to achieve the S/NW values as noted. A different PC/SC ratio will change these values.
24. Measurements taken with SAW filter G1984 (Siemens) for vision and sound IF (sound shelf: 14 dB).
Picture-to-sound carrier ratio of transmitter PC/SC = 13 dB. Input level on pins VIF1 and VIF2 of
Vi(SIF) = 10 mV (RMS) sync level, 27 kHz FM deviation for sound carrier, fAF = 400 Hz. Measurements in accordance
with
“CCIR 468”. De-emphasis is 50
s.
25. The QSS signal output on pin SIOMAD is analysed by a test demodulator TDA9820. The S/N ratio of this device is
more than 60 dB, related to a deviation of
±27 kHz, in accordance with “CCIR 468”.
26. Measurements taken with SAW filter K3953 for vision IF (suppressed sound carrier) and K9453 for sound IF
(suppressed picture carrier). Input level Vi(SIF) = 10 mV (RMS), 27 kHz (54 % FM deviation).
27. Measurements taken with SAW filter K9453 (Siemens) for AM sound IF (suppressed picture carrier).
28. The value of Cx determines the accuracy of the resonance frequency of the crystal. It depends on the type of crystal
used.
29. Pin REF is able to operate as a 1-pin crystal oscillator input as well as an external reference signal input, e.g. from
the tuning system.
30. The SDA and SCL lines will not be pulled down if VCC is switched off.
31. The AC characteristics are in accordance with the I2C-bus specification for fast mode (maximum clock frequency is
400 kHz). Information about the I2C-bus can be found in the brochure
“The I2C-bus and how to use it” (order number
9398 393 40011).
32. Port P1 and port P2 are open-collector outputs.
