Microchip Technology EX-421
The EX-421 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 OCXO’s and smaller TCXO’s. The EX-421 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.| Part No. | EX-421 |
