Fort Myers, FL - January 5, 2012 - Crystek Corporation has launched the CCHD-957, a new Ultra-Low Phase Noise HCMOS Clock Oscillator with Standby Mode, featuring an extremely low close-in phase noise of -100 dBc/Hz @ 10 Hz offset and a typical noise floor of -170 dBc/Hz @ 100 kHz offset. This performance makes Crystek’s HCMOS Clock Oscillator family an industry-leading 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 Crystek CCHD-957 HCMOS Clock Oscillator also features 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 family is housed in a 9x14 mm SMD package and operates with a +3.3 V power supply consumring 15 mA of current. Stability is rated at ±20 to ±50 ppm (0°C to +70°C) and ±25 to ±50 ppm (-40°C to +85°C).
The CCHD-957 generates frequencies between 10 MHz and 50 MHz. Its output driver is capable of driving ±24 mA, translating to a rise/fall time of ~3 ns Max at 20% to 80% Vcc with a 15 pF load.
The Crystek CCHD-957 HCMOS Clock Oscillator is made in the U.S.A. and available from Crystek’s stocking distributors.
