Hello, Ulrich was asking about 10 MHz oscillators. We make a 10 MHz OXCO that has –118 dBc @ 1 Hz with a –175 dBc noise floor. Not cheap though. Also Low G sensitive oscillators. 5 x 10E-11/g. Contact me off list as I’m trying not to advertise on this forum. Best Regards Martyn martyn at ptsyst.com *****************************************
