The Statek MTXO tight stability crystal oscillators offer fundamental frequencies from 10 to 50MHz with a total frequency tolerance as low as ±5ppm (including first year ageing) over the military temperature range from -55 to +125°C.
Versions offering high shock resistance up to 75,000g – designated MTXOHG – are also available.
Housed in a compact 3.2 x 2.5mm hermetically sealed ceramic package, MTXO crystal oscillators also offer ultra-low period jitter of 1.7ps (RMS) with ultra-low Allan deviation and phase jitter. Suitable for reflow soldering at maximum process temperature of 260°C for 20 seconds, the new MTXOs offer CMOS output into 10pF load with clipped sinewave option available.
Additional specifications include low acceleration sensitivity, start-up time of 5ms maximum, rise/fall time of 5ns maximum with duty cycle of 45% minimum, 55% maximum.
Supply voltage requirement is 3.3V DC ±10% with typical supply current of just 3mA. Optional military testing is per MIL-PRF-55310 level B with industrial temperature range versions also available. Supply packaging options are tray pack or tape-and-reel per EIA 481.
These new oscillators are intended for use in a wide range of industrial, defence and aerospace-related applications including RF telemetry, master clock, telecommunications, navigation and handheld devices and instrumentation.
