CCHD-575-50-80.000

Model CCHD-575 is the industry’s lowest jitter clock oscillator in a 5×7.5 mm package. It features a
typical phase jitter of 82fs RMS at 100 MHz. Close-in phase noise is -90 dBc/Hz @ 10 Hz while its
floor is at -168 dBc/Hz. This oscillator may be small in size but it packs a punch inside. Its output
driver is capable of driving ±24mA. This translates to a rise/fall time of ~600ps at 100 MHz with a
15pF load.
