TDA9884
I2C-bus controlled multistandard alignment-free IF-PLL
[1]
Values of video and sound parameters can be decreased at VP = 4.5 V.
[2]
For applications without I2C-bus, the time constant (R
× C) at the supply must be > 1.2 s (e.g. 1 and 2.2 F).
[3]
Condition: luminance range (5 steps) from 0 % to 100 %.
[4]
AC load: CL < 20 pF and RL >1k. The sound carrier frequencies (depending on the TV standard) are attenuated by the integrated
sound carrier traps (see Figure 16 to Figure 21;
H (s) is the absolute value of transfer function).
[5]
Measurement using unied weighting lter (“
ITU-T J.61”), 200 kHz high-pass lter, 5 MHz low-pass lter and subcarrier notch lter
(“
ITU-T J.64”).
[6]
The intercarrier output signal at pin SIOMAD can be calculated by the following formulae taking into account the internal video signal
with 1.1 V (p-p) as a reference:
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).
[7]
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.
