Ordering Information
Product name + variant + option codes + frequency
Option codes must be included to properly specify a model.
eg: GTXO-71V/JS 13.00MHz ±2.5ppm -30+75°C TCXO with VC
GTXO-71T/HN 14.40MHz ±2.0ppm -20+70°C TCXO no VC
Option code X (eg GTXO-71V/X) denotes a custom spec.
ͷ 1: Will operate within specification on any supply voltage from
+2.7V to +5.5V.
ͷ 2: The output is not DC-free. A coupling capacitor (10nF) may be
required.
