Notes to the “Characteristics”
1. It is possible to start the horizontal oscillator when a current of 5.5 mA is supplied to this pin. In this condition the main
part of the IC is not active and this results in the frequency of the oscillator not being controlled at the correct value.
Consequently, the oscillator frequency will be higher than normal, the maximum deviation will be 75%. When the
start-up function is used the maximum voltage on pin 36 must be limited to 8.8 volts.
2. On set AGC.
3. This parameter is not tested during production and is just given as application information for the designer of the
television receiver.
4. Measured at 10 mV RMS top sync input signal.
5. So called projected zero point, i.e. with switched demodulator.
6. Measured in accordance with the test line given in Fig.11. For the differential phase test the peak white setting is
reduced to 87%.
The differential gain is expressed as a percentage of the difference in peak amplitudes between the largest and
smallest value relative to the subcarrier amplitude at blanking level.
The phase difference is defined as the difference in degrees between the largest and smallest phase angle.
7. This parameter is not tested during production but is guaranteed by the design and qualified by means of matrix
batches which are made in the pilot production period.
8. This figure is valid for the complete video signal amplitude (peak white-to-black), see Fig.12.
9. Insertion (suppression of the interference pulses) to a level of 2.6 V is active only during a strong input signal.
This is because the noise inverter has a negative effect on the sound performance at a weak input signal.
10. The test set-up and input conditions are given in Fig.13. The figures are measured with an input signal of
10 mV RMS.
