It features a typical low close-in phase noise of -100 dBc/Hz @ 10 Hz offset, and a noise floor of -169 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. 49.152 MHz HCMOS 3.3V45.1584 MHz HCMOS 3.3V Digital Audio Broadcasting (DAB) Professional CD audio equipment DACs and ADCs for HD audio 22.5792 MHz HCMOS 3.3V 24.576 MHz HCMOS 3.3V Applications include:
