Statek

Frequency control specialist Euroquartz has launched a new low-profile, differential output crystal oscillator (DFXO) from Statek, designed for use in applications requiring low jitter and ultra-high frequency differential outputs in a small footprint.

Available in frequencies from 20 to 300MHz (fundamental mode), the new DFXO is available in standard 6-pad 5 x 7mm surface mount packages measuring just 1.75mm or 1.85mm-high depending on terminations. Designed for operation over the temperature range -40°C to 105°C, the new Statek DFXO offers LVDS, LVPECL or CMOS outputs with low phase noise (-148dBc/Hz at 100kHz) and typical integrated timing jitter of 0.3ps (both for LVDS output).

Frequency stability is approximately 100ppm over full temperature range (approximately 50ppm over -40°C to 85°C) as standard with tighter tolerances (approximately 25ppm) available to order. A tri-state enable/disable option is also available.

Standard supply voltage is 3.3V ±10% with 2.5V ±10% available and no external decoupling capacitor is required with optional internal capacitor of 0.01µF. Additional specifications include shock survival of 5000g (0.3ms, ½ sine) and vibration survival of 20g (10Hz to 2,000Hz swept sine). Ageing is ±5ppm for first year depending on frequency.

The new Statek DFXO from Euroquartz is supplied in tray packs or tape and reel for surface mount applications with maximum process temperature of 260°C for ten seconds.

Applications include military and aerospace avionics, communications and networking.
