Ultra-Low Phase Noise HCMOS VCXO Provides High-Performance Frequency Control for HD Audio Equipment

Ultra-Low Phase Noise HCMOS VCXOCrystek Corporation has launched the CVHD-957, a new Ultra-Low Phase Noise HCMOS Voltage-Controlled Ocillator (VCXO) with Standby Mode, featuring an extremely low close-in phase noise of -90 dBc/Hz @ 10 Hz offset and a typical noise floor of -168 dBc/Hz @ 100 kHz offset. This performance makes Crystek’s HCMOS VCXO family an industry-leading choice for use in applications such as: digital audio broadcasting (DAB), professional CD audio equipment, and digital-to-analog converters (DACs) and analog-to-digital converters (ADCs) for HD audio.

The Crystek CVHD-957 HCMOS VCXO 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 9×14 mm SMT package and operates with a +3.3 V power supply consuming 15 mA of current. Stability is rated at ±100 ppm. The CVHD-957 generates frequencies between 10 MHz and 50 MHz.

The Crystek CVHD-957 HCMOS Clock Oscillator is made in the U.S.A. and available from Crystek’s stocking distributors. More information is available at www.crystek.com.
