Available in a frequency range from 40MHz to 200MHz, and designed for 2.5V or 3.3V supply, these oscillators offer femtosecond integrated phase jitter performance (200fs typical) with an ultra-low phase noise of -138dB/Hz at 10kHz offset.
HCK5361 differential HCSL oscillators are housed in 5 x 3.2 x 1.2mm 6-pad surface mount packages, while HCK5761 parts are in 7 x 5 x 1.8mm housings. Ageing for both types is less than ±3ppm per year maximum at 25°C ambient temperature. The oscillators are RoHS 6/6 (2002-95/EC) and WEEE (2002/96/EC) compliant.
