Functional Description
The following sections provide brief descriptions of the MC44C401L modules.
7.1 Phase Locked Loop (APLL)
The APLL, shown in Figure 5, locks to the reference frequency of 12 MHz and generates the master clock.
Figure 5. APLL and Clock Generator
7.2 Sync Separator
The Sync Separator, shown in Figure 6, extracts the composite sync from the incoming composite video signal.
The composite sync is used by the Audio Processor to generate the 15.734 kHz pilot tone and the 31.468 kHz carrier
to modulate the Left-Right channel. The nominal output level of composite video signal sources is 1 Vpp on 75
and the sync amplitude is 0.3 V.
