[1] Values of video and sound parameters can be decreased at V_P= 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; C_L< 20 pF and R_L> 1 kΩ. 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/N_Wweighted 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

V_i(SC)

1.1 V (p-p) as a reference: V_o(intc)(rms)= 1.1 ×
