Low-power 32.768kHz TCXO

Paul Boughton

Euroquartz has introduced the EME83 series 32.768kHz TCXO which is a 32.768kHz CMOS output TCXO with a maximum frequency stability of ±5ppm (±2.62 minutes/year) over the operating temperature range -40° to +85°C.

A proprietary temperature compensation technique is applied to the built-in X-Cut 32.768kHz tuning fork crystal and temperature sensor.

A 400nA current compensation makes it suitable for battery operated devices. The TCXO is packaged in a 7 x 5 x 1.8mm package, ideal for miniaturised applications. The part is designed for long-term frequency reference applications.

Application areas include: Frequency Reference for real time clocks (RTC); Portable instrumentation; tTiming synchronisation for networks, servers, hubs, routers and switches; timing reference input for various energy metering ICs; smart metering, data loggers; GPS receivers, telematics.
