The Crystek CCHD-957 Low Phase Noise Oscillator with standby mode is a 10MHz to 50MHz HCMOS Clock Oscillator designed specifically for High Definition Audio (HD Audio). It features a typical low close-in phase noise of -100dBc/Hz at 10Hz offset, and a noise floor of -169 dBc/Hz. With the extremely low phase noise performance, the user will “hear the difference”. The CCHD-957 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 a Tri-State condition. Input voltage is 3.3Vdc, consuming 15mA typical. The oscillator is offered in three temperature ranges, up to -40°C to +85°C. The industry standard 9mm × 14mm surface mount package makes it compatible with most pick and place lead free processes.
