CCHD-957 Model
9×14 mm SMD, 3.3V, HCMOS
22.5792 MHz HCMOS 3.3V

45.1584 MHz MOS 33V
49.152 MHz HCMOS 3.3V
Crystek’s 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 9×14 mm SMT package and operates with a
+3.3V power supply.
