P-379 Processor

3.0 DESCRIPTION AND SPECIFICATIONS

General Description

The P-379 contains the latest in television electronics, including synthesized crystal-

referenced phase-locked-loop oscillators, microprocessor control, saw-filtered if and

hybrid amplifiers. In addition to these features, the U.S. version contains automatic input

offset programming to remove input offsets inherent to off-air channels (0, ±10KHz),

cable standard channels (0, +12.5KHz, +25KHz) and Cable HRC channels (0.3KHz

master oscillator offset).
