ex-400 evacuated miniature crystal oscillator the ex-400 provides exceptionally low aging rates and tight temperature stabilities in an extremely small package over a wide range of environmental conditions. this emxo series bridges the gap between current large, high precision ocxos and smaller tcxos. the ex-400 series becomes the most economical choice where there is a need for spectral purity, short and long term stability, along with small size and dramatically reduced power consumption. vectron international ? 267 lowell road, hudson, nh 03051 ? tel: 1-88-vectron-1 ? http://www.vectron.com 4-pin dip ? uses doubly rotated crystal ? low power consumption: <0.35 watts @ +25c ? previous model number: ex-380, ex-381, ex-385 series ? frequency range: 10 mhz - 80 mhz ? sonet/sdh, dwdm, fdm, atm, 3g ? telecom transmission and switching equipment ? wireless communication equipment ? military airborne and mobile systems ? features applications description ex-400 frequency stabilities 1 parameter min typ max units condition vs. operating temperature range (refer- enced to +25c) -75 -100 -100 -150 -150 -150 -250 -250 -250 -500 -500 -500 +75 +100 +100 +150 +150 +150 +250 +250 +250 +500 +500 +500 ppb ppb ppb ppb ppb ppb ppb ppb ppb ppb ppb ppb -20 +70c (10 to 20.49 mhz) -20 +70c (10 to 50 mhz) -40 +85c (10 to 20.49 mhz) -20 +70c -40 +85c -55 +85c (10 to 50 mhz) -20 +70c -40 +85c -55 +85c -20 +70c -40 +85c -55 +85c performance speci! cations
