F860
The MACOM F860 is a professional re-broadcast grade microprocessor controlled phase-locked loop synthesized single
channel audio-video modulator available with an optional BTSC stereo encoder. The F860 provides 60 dBmV minimum output
while accommodating HRC and IRC offset frequencies. The optional BTSC encoder enables delivery of high fidelity stereo
without the cost of a stand-alone stereo encoder. This cost-effective modulator was designed for use in heavily loaded systems
requiring high stability and superior picture and stereo sound quality. Its phase-locked loop frequency control and superior SAW
filtering enhance stability, minimize adjacent channel interference and assure accurate and spurious free output. Superior out-of-
band carrier-to-noise performance is achieved through band-pass filtering at the output amplifier. The modulator is shipped with all
internal adjustments preset. FCC Docket 21006 offsets are standard. The MACOM line is backed by an industry leading 5-year
limited warranty.
