New oscillator provides high performance for HD audio equipment

This device’s performance makes Crystek’s HCMOS Clock Oscillator family suitable for use in applications such as: DACs (digital-to-analogue converters), ADCs (analogue-to-digital converters), DAB (digital audio broadcasting), and professional CD audio equipment.

The CCHD-957 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 +3.3V 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.
