Functional Description
7 Functional Description
The following sections provide brief descriptions of the MC44C401 modules.
7.1 Phase Locked Loop (APLL)
The APLL 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 V
pp
on 75
and the sync amplitude is 0.3 V.
