I2C-bus controlled multistandard alignment-free IF-PLL demodulators
[1]
Values of video and sound parameters can be decreased at VP = 4.5 V.
[2]
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).
[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 TV standard) are attenuated by the integrated sound
carrier traps (see Figure 15 to Figure 20;
H (s) is the absolute value of transfer function).
[5]
S/N is the ratio of black-to-white amplitude to the noise voltage (RMS value measured on pin CVBS and tested at video black level,
‘quiet line’). Noise analyzer settings: B = 5 MHz, 200 kHz high-pass and sound carrier trap on. In case of S/NW weighted in accordance
with
“ITU-T J.61”. Measurements taken for B/G standard.
[6]
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:
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).
