Euroquartz has introduced a new range of high-performance surface-mount clock oscillators offering high precision and high temperature stability.
Offering frequencies from 1,0 to 56,0 MHz, the new XOR91 series exhibits phase noise performance of
-145 dBc/Hz at 10 kHz and -150 dBc/Hz at 100 kHz, and integrated phase jitter of 300 fs typical, 12 kHz to 20 MHz.
Housed in a 7 x 5 mm SMD package, the new oscillators operate from 1,8 V, 2,5 V or 3,3 V supply and offer frequency stability from ±7 ppm over the commercial temperature range (-10°C to +70°C) to ±15 ppm over the industrial temperature range (-40°C to +85°C).
Specifications include output logic LVCMOS, output load of 15 pF, rise/fall time of 2 ns typical, startup time 0,6 ms typical (1 ms maximum), output symmetry of 50% ±5%, tristate function implemented as standard and ageing of ±2 ppm/year maximum for first year. Storage temperature range is -55°C to +150°C. The parts are available on tape and reel and feature a maximum process temperature of
