Low phase noise clock oscillator targets HD audio
This performance makes this 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 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 9- x 14-mm SMT 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 around 3 ns maximum at 20% to 80% Vcc with a 15 pF load.
