CVHD-957 Model 9×14 mm SMD, 3.3V, HCMOS CVHD-957 Ultra-Low Phase Noise VCXO with Standby Mode e h T r ! a ! e e c H n e r e f f i D Crystek’s Model CVHD-957 HCMOS VCXO family has been designed specifically for High Definition Audio (HD Audio). It features a typical low close-in phase noise of -90 dBc/Hz @ 10 Hz offset, and a noise floor of -168 dBc/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 completely 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.
