Clock Oscillator controls frequency for HD audio equipment.
Press Release Summary:
Featuring close-in phase noise of -100 dBc/Hz at 10 Hz offset and typical noise floor of -170 dBc/Hz at 100 kHz offset, Model CCHD-957 is suited for DACs, ADCs, DAB, and professional CD audio equipment. HCMOS clock oscillator includes Standby Function - when placed in disable mode, internal oscillator is completely shut down and output buffer is placed in Tri-State. Housed in 9 x 14 mm SMT package, device operates with +3.3 V power supply and generates frequencies from 10-50 MHz.
Original Press Release:
Ultra-Low Phase Noise Clock Oscillator from Crystek Provides High-Performance Frequency Control for HD Audio Equipment
Fort Myers, FL - 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 @ 10Hz offset and a typical noise floor of -170 dBc/Hz @ 100kHz 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 SMT package and operates with a +3.3V power supply consumring 15mA of current. Stability is rated at 20-50ppm (0°C to +70°C) and ±25-50ppm (-40°C 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% to 80% Vcc with a 15pF load.
The Crystek CCHD-957 HCMOS Clock Oscillator is made in the U.S.A. and available from Crystek's stocking distributors. For pricing details, contact Crystek Corporation.
