Hi-Performance Clock Osc. from Crystek
SMT crystal clock oscillator.
Fort Myers, FL — Crystek Corporation has launched the CCHD-957, a new ultra-low phase noise HCMOS clock oscillator with standby mode, with an extremely low close-in phase noise of -100dBc/Hz at 10Hz offset and a typical noise floor of -170dBc/Hz at 100kHz offset. This performance makes the oscillator family an excellent choice for use in applications such as: DACs (digital-to-analog converters), ADCs (analog-to-digital converters), DAB (digital audio broadcasting), and professional CD audio equipment.
The oscillator also has a "Standby Function" — when placed in disable mode, the internal oscillator is completely shut down and its output buffer is placed in Tri-State. This oscillator family is housed in a 9 x 14mm SMT 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 ±25-50ppm (-40 to +85°C).
The CCHD-957 generates frequencies between 10MHz and 50MHz. Its output driver is capable of driving ±24mA, translating to a rise/fall time of ~3nsec Max at 20 percent to 80 percent Vcc with a 15pF load.
