FS6219 monolithic CMOS clock generator designed minimize cost component count digital video audio systems. fully independent VCXOs permit accurate simulaneous phase locking generated clocks independent sources, such satellite cable delivered video terrestrial broadcasts. Three fully independent, fully programmable PLLs with flexible post-dividers permit generation desired clock frequencies precisely, with added "synthesis" errors. FS6219 makes latest technology clock period jitter cumulative jitter. ADDR permits FS6219 uniquely con2 trolled single bus. full read/write slave capability FS6219 allows device programming completely verified. Contact factory custom requirements.
