SC10 Ovenized Crystal Oscillator
|
The SC10 is a high stability ovenized 10 MHz quartz oscillator that combines excellent phase noise, Allan variance, and aging characteristics. Using an SC-cut crystal for lowest phase noise characteristics, and an innovative "electronic double oven" temperature controller to minimize temperature gradients, the SC10 achieves a one second Allan variance of |

Convenient Options
A number of options can be specified to match the SC10's performance to your requirements. +15 or +24 VDC operation can be specified, and the output is available on SMA, SMB, and SMC connectors, or on a single pin. Aging, noise, temperature stability, and operating temperature range can all be separately specified in one of three grades so you only pay for the performance you need. The electronic fine tuning (EFC) is available with a number of tuning ranges and slopes.
