Model CVHD-575 is the industry’s lowest phase noise VCXO in a 5×7.5 mm package. Close-in phase
noise is -90 dBc/Hz @ 10 Hz while its floor is at -165 dBc/Hz. This oscillator may be small in size but
it packs a punch inside. Its output driver is capable of driving ±24mA.
Applications include
Digital Video, DACs, ADCs for HD Audio,
Low Phase Signal Sources, Test and Measurement
