SL5162
open collector outputs is initially turned on. This is then
released when the mode selection (PAL/NTSC or SECAM) is
made or at any other convenient point (e.g. when frequency
data is sent) in PAL/NTSC mode. As an example, to synthesise
471·25MHz send the data words as shown in Table 4.
Care must be taken to ensure that the MSS pin is adequately
decoupled as close to the pin as possible. The routing of any
control line to this pin should also be layed out to ensure
maximum separation from the LO components whilst still
remaining as short as possible. In PAL/NTSC (mono)
applications, pin 13 (SUB 2) may be left open circuit or
decoupled to ground via a 1nF capacitor. In SECAM (mono)
applications pin 13 must be directly connected to V
to
disable the intercarrier sound circuitry. For optimum
performance it is recommended that in single ended output
applications, pin15 is used for positive modulation, and pin 16
used for negative modulation.
Test Signal Generator (TSG)
A TSG is provided which may be enabled by connecting a
500kHz ceramic resonator via a 56pF capacitor to the TSG
pin (pin 18) as shown in Figure 4. The TSG is disabled by
connecting pin 18 to ground. The waveform that the TSG
produces (shown in Figure 3) will create two white bars on a
standard TV screen. It should be noted that standard (video)
modulation depth specification for the SL5162 in its normal
application does not apply to the TSG facility, since it is only
intended as a tuning or test mode.
AGC/White Clip
The SL5162 is provided with an AGC circuit which should
ensure correct modulation depth provided a composite video
signal between 0·5V and 1·5V sync tip to peak white is applied
to the VIDEO input, pin 19. If desired, the AGC may be
disabled and a white clip circuit switched in to prevent
overmodulation. This clipping level is set to a nominal 17%
above peak white level, thus ensuring that even with a
standard PAL I 95% saturated, 100% amplitude colour bars
test signal, no clipping should take place. The AGC is enabled
by connecting the pin 20 to Ground via a 150nF capacitor;
white clip is enabled by connecting a 1·6k
resistor from pin
20 to ground.
