Precision low jitter oscillators

June 10, 2013 // By Graham Prophet
Frequency control specialist Euroquartz has launched two ranges of high-precision low-jitter oscillators that are available on very short delivery leadtimes and offer a low cost and technically superior solution for new and existing designs.

Typically available in as little as five to 10 days, the HTQF and HPQF series have been developed as precision frequency control components providing CMOS (HTQF) and LVPECL (HPQF) output clock oscillators offering low current consumption, wide operating frequency ranges and an integrated phase jitter performance of 1.0 psec and 0.6 psec rms respectively. Both series are housed in a choice of two industry-standard surface mount packages, 7 x 5 mm and 5 x 3.2 mm.

HTQF series LVCMOS oscillators are available with frequency range from 10 to 245 MHz with frequency stability of ±50 ppm over -40 to +85°C. Current consumption is less than 18 mA at 50 MHz. Output load is 15 pF.

HPQF series LVPECL oscillators are available with frequency range from 10 to 1450 MHz with frequency stability of ±50 ppm over -40 to +85°C. Current consumption is less than 46 mA at 100 MHz and output load is differential. Both series are available with 2.5 or 3.3V supply voltage and feature tristate function to conserve power.
