270 Series OCXO


The 270 Series is an ultra high stability, high reliability double oven controlled crystal oscillator (OCXO). This series of oscillators is designed with the industry standard Euro CO-08 footprint and is a drop in replacement for the 230 Series OCXO product line. This allows the system performance to be upgraded to meet new demanding requirements without the need for a redesign. Housed in a 1.423"L x 1.071"W x 0.765"H (36.1 x 27.2 x 19.4mm) package, the 270 Series OCXO offers the same ultra high stability as our 260 Series OCXO with a higher MTBF. The 270 Series OCXO boasts a thermal stability performance of 2.0E-10 to 5.0E-09 over a 100°C ambient temperature range rivaling Rubidium atomic clock performance.
