New Surface-mount HCSL Oscillators Targeting Volume Applications From Saelig

Pittsford, NY, USA: Saelig Company, Inc. (Saelig) ( has introduced a new range of surface-mount high-speed current steering logic (HCSL) oscillators designed for volume applications. The new HCK5361 and HCK5761 differential HCSL oscillators are highly competitive and deliver higher frequencies compared with surface acoustic wave (SAW)-based oscillator designs. The new parts offer jitter performance of less than 1ps (12kHz to 20MHz), an operating temperature range of -40 to +85°C and provide low aging.

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.
