Ordering Information
Product name + variant + option codes + frequency
Option codes must be included to properly specify a model.
eg:
GTXO-81V/JS 13.00MHz
±2.5ppm -30+75C, TCXO with VC
GTXO-81T/HN 14.40MHz
±2.0ppm -20+70C, TCXO no VC
Option code X (eg GTXO-81V/X) denotes a custom spec.
Available on T&R - 1k pcs per reel.
Will operate within specification on any supply voltage from +2.7V
to +5.0V.
WARNING!
Although this product does not contain lead, it is NOT designed to
withstand 260C soldering processes
