Multistandard hybrid IF processing
[1]
Values of video and sound parameters can be decreased at VP = 4.5 V.
[2]
AC load; CL < 20 pF and RL >1k. The sound carrier frequencies (depending on TV standard) are attenuated by the integrated sound
carrier traps.
[3]
Condition: luminance range (5 steps) from 0 % to 100 %. Measurement value is based on 4 of 5 steps.
[4]
The sound carrier trap can be bypassed by setting the I2C-bus bit W2[0] to logic 0; see Table 23. In this way the full composite video
spectrum appears at pin CVBS. The video amplitude is reduced to 1.1 V (p-p).
[5]
Measurement using 200 kHz high-pass lter, 5 MHz low-pass lter and subcarrier notch lter (
“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.
[7]
With single-ended load for fIF < 45 MHz RL ≥ 1k and CL ≤ 5 pF to ground and for fIF = 45 MHz to 60 MHz RL =1k and CL ≤ 3 pF to
ground.
[8]
This parameter is not tested during production and is only given as application information.
[9]
Noise level is measured without input signal but AGC adjusted corresponding to the given input level.
[10] Set with AGC nominal output voltage as reference. For C/N measurement switch input signal off.
[11] The tolerance of the reference frequency determines the accuracy of VIF AFC, RIF AFC, FM demodulator center frequency, maximum
FM deviation, sound trap frequency, LIF band-pass cut-off frequency, as well as the accuracy of the synthesizer.
