New oscillators feature wide operational temperature range and more

29-01-2015 | Euroquartz | Passives

Latest from Euroquartz is a range of oscillators that offer wide operating
temperature range, femtosecond integrated phase jitter and superior phase
noise performance.

The XON91 and XON53 oscillators offer frequencies from 1.25MHz to 60MHz and
are capable of withstanding temperatures from -55C to +125C. Phase jitter is
typically 500fs from 12kHz to 20MHz integrated. The XON91 series devices
are available in 7mm x 5mm x 1.8mm surface-mount packages while XON53
devices come in 5m x 3.2mm x 1.2mm 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
new oscillators offer stability of ±100 or ±50ppm over the specified
operating temperature range and also offer excellent phase noise performance
(from -85dB/Hz typical at 10Hz to -155dB/Hz at 10MHz). Versions of both
ranges are available for operation from 1.8, 2.5, 3.3 and 5V supplies with
current consumption as low as 7mA depending on frequency.

Additional specifications include rise times of 7ns or 10ns maximum
depending on supply voltage, 15pF load, start-up time of 5 or 10ms depending
on frequency and ageing of ±2ppm maximum for first year. Solder profile is
260C maximum.
