Featuring a low close-in phase noise of -100dBc/Hz at 10Hz offset and a typical noise floor of -170dBc/Hz at 100kHz offset, the CCHD-957 is for DACs and ADCs, DAB and professional CD audio equipment. The oscillator from Crystek is an HCMOS oscillator with standby mode. When placed in disable mode, the internal oscillator is completely shut down and its output buffer is placed in tri-state. The oscillator is housed in a 9x14 mm surface mount package and operates with a +3.3V power supply consuming 15mA of current. Stability is rated at 20 to 50ppm (0 to +70°C) and ±25 to 50ppm (-40 to +85°C). The oscillator generates frequencies between 10 and 50MHz. Its output driver is capable of driving ±24mA, translating to a rise/fall time of approximately 3nsec maximum at 20 to 80% Vcc with a 15pF load.
