Euroquartz launches new surface mount precision oscillators

Frequency control specialist, Euroquartz has introduced a new range of high performance surface mount clock oscillators offering high precision and high temperature stability.

Offering frequency range from 1.0 to 56.0MHz, the new XOR91 oscillators exhibit superior phase noise performance of -145dBc/Hz at 10kHz and -150dBc/Hz at 100kHz and integrated phase jitter of 300fs typical, 12kHz to 20MHz.

Housed in a 7 x 5mm SMD package, the new XOR91 oscillators operate from 1.8, 2.5 or 3.3V supply voltage and offer frequency stability from ±7ppm over commercial temperature range (?10 to +70°C) to ±15ppm over industrial temperature range (?40 to +85°C).

Specifications include output logic LVCMOS, output load of 15pF, rise/fall time of 2ns typical, start-up time 0.6ms typical, 1ms maximum, output symmetry of 50% ±5%, tristate function implemented as standard and ageing of ±2ppm/year maximum for first year. Storage temperature range is -55 to +150°C.

Ideal for use in high precision clock applications, the new XOR91 oscillators are available on tape and reel and feature maximum process temperature of 260°C for 10s.

Euroquartz is an independent UK-based manufacturer and supplier of quartz crystals, oscillators, filters and frequency-related products to the electronics manufacturing industry worldwide. The company designs and manufactures a comprehensive range of frequency control components for a wide range of customers including major OEMs in a broad spectrum of applications including military and aerospace, communications, general electronics, computing, control systems and petrochemical among many others.
