[1] Values of video and sound parameters can be decreased at V_P= 4.5 V.

[2] 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.

[3] The sound carrier trap can be bypassed by setting the I²C-bus bit W2[0] to logic 0; see Table 24. In this way the full composite video

spectrum appears at pin CVBS. The video amplitude is reduced to 1.1 V (p-p).

[4] Condition: luminance range (5 steps) from 0 % to 100 %. Measurement value is based on 4 of 5 steps.

[5] Measurement using 200 kHz high-pass ﬁlter, 5 MHz low-pass ﬁlter and subcarrier notch ﬁlter (“ITU-T J.64”).

[6] To match the AFC output signal to different tuning systems a current output is provided. The test circuit is given in Figure 19. The

AFC steepness can be changed by resistors R1 and R2.
