Oscillators offer wide operating temperature range, femtosecond phase jitter
The XON91 and XON53 oscillators offer frequencies from 1.25 to 60 MHz and are capable of withstanding temperatures from -55 to +125°C. Phase jitter is typically 500 fs from 12 kHz to 20 MHz integrated. XON91 series oscillators are available in 7- x 5- x 1.8-mm surface mount packages while XON53 devices are in 5- x 3.2- x 1.2-mm miniature housings. Both feature a standard 4-pad layout.
Ideal for use in a wide range of applications, including military COTS (commercial off-the-shelf) projects and industrial control systems, these oscillators offer stability of ±100 or ±50ppm over the specified operating temperature range and also offer excellent phase noise performance (from -85 dB/Hz typical at 10 Hz to -155 dB/Hz at 10 MHz). Versions of both ranges are available for operation from 1.8, 2.5, 3.3 and 5 V supplies with current consumption as low as 7 mA depending on frequency.
Additional specifications include rise times of 7 ns or 10 ns maximum depending on supply voltage, 15 pF load, start up time of 5 or 10 ms depending on frequency and ageing of ±2ppm maximum for first year. Solder profile is 260°C maximum.
