MC44145 PIXEL CLOCK GENERATOR / SYNC SEPARATOR

Composite Sync Separator The composite sync separation section is comprised of two blocks, a sync slicer and a sync amplifier, which can be used to extract the vertical sync and composite sync information from a video signal. The sync separator is an adaptive slicer in which the video signal is slig.

The MC44145 contains a sync separator with composite sync and vertical outputs, and clock generation circuitry for the digitization of any video signal along with the necessary circuitry for clock generation, such as a phase comparator and a divide by 2 to provide a 50% duty cycle. The MC44145 is available .

MC44145 Features

* ed at the output of the VCO, thus allowing for a precise 50% duty cycle, hence the VCO is operating at twice the required frequency. The divider can be bypassed, bringing the VCO output directly to the output buffer. The external divider must provide a feedback pulse to close the loop; the falling e
