Ordering Information
Product name + variant + option codes + frequency
Option codes must be included to properly specify a model.
eg: GTXO-253V/JS 13.00MHz ±2.5ppm -30+85°C, TCXO with VC
GTXO-253T/HN 14.40MHz ±2.0ppm -20+75°C, TCXO no VC
Option code X (eg GTXO-253V/X) denotes a custom spec.
 ±0.5ppm over -30+85°C is not available in V variant (VC-TCXO)
