RSG CX9CSM4 14 mhz to 250 mhz low profile, ultra-miniature surface mount at quartz crystal Datasheet

CX9SM AT CRYSTAL
14 MHz to 250 MHz
Low Profile, Ultra-Miniature
Surface Mount AT Quartz Crystal
™
DESCRIPTION
Designed and manufactured in the USA, Statek’s CX9SM
AT quartz crystal is the newest device available in frequencies
ranging from 14 MHz to 250 MHz. This device has been
specifically designed for applications requiring a very small
foot print and low profile. It is 4.1 mm x 1.5 mm with a height
under 1 mm. Using micro-machining processes, this
surface-mountable crystal is hermetically sealed within an
ultra-miniature ceramic package to ensure high stability and
low
aging.
Tight
calibration
and
excellent
frequency/temperature stability make the CX9SM ideally
suited for many high frequency applications.
