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.
1: Will operate within specification on any supply voltage from
+2.7V to +5.5V.
2: The output is not DC-free. A coupling capacitor (10nF) may be
required.
