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

Other frequencies available. Please consult our sales office.

Option code X (eg GTXO-253V/X) denotes a custom spec.

1:ꢀ±0.5ppm over -30+85°C is not available in V variant (VC-TCXO)

2:ꢀThe output is not DC-free. A coupling capacitor (10nF) may be

required.
