CCHD-957 Ultra-Low Phase Noise Oscillator CCHD-957 Model with Standby Mode 914 mm SMD, 3.3V, HCMOS 22.5792 MHz HCMOS 3.3V 24.576 MHz HCMOS 3.3V 45.1584 MHz HCMOS 3.3V 49.152 MHz HCMOS 3.3V Crysteks Model CCHD-957 HCMOS CLOCK oscillator family has been designed specifically for High Definition Audio (HD Audio). It features a typical low close-in phase noise of -100 dBc/Hz 10 Hz offset, and a noise floor of -169 dBc/Hz. With this extreme low phase noise performance, you will Hear the Difference. It also features a Standby Function, that is, when placed in disable mode, the internal oscillator is completely shut down in addition to its output buffer being placed in Tri-State. This family is housed in a 914 mm SMT package and operates with a +3.3V power supply.
