CVHD-957
CVHD-957 is Ultra-Low Phase Noise VCXO manufactured by CRYSTEK.
features a typical low close-in phase noise of -90 d Bc/Hz @ 10 Hz offset, and a noise floor of
-168 d Bc/Hz. With this extreme low phase noise performance, you will “Hear the Difference”. It also features a
“Standby Function”, that is, when placed in disable mode, the internal oscillator is pletely shut down in addition to its output buffer being placed in Tri-State. This family is housed in a 9×14 mm SMT package and operates with a
+3.3V power supply.
