EME83 SERIES TCXO

32.768kHz

Low Power (nA Current Consumption)

FEATURES

EME83x 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. This time-keeping accuracy is

outstanding in the industry.

A proprietary temperature compensation technique is applied to the built-in X-Cut 32.768kHz

tuning fork crystal and temperature sensor.

OUT

A 400nA current compensation (average f

operated devices.

≤128Hz, 4 min TMP.) makes it ideal for battery

The TCXO is packaged in a 7 x 5 x 1.8mm package, ideal for miniaturized applications.

Designed for long-term frequency reference applications.

APPLICATIONS

Frequency Reference for real time clocks (RTC).

Portable instrumentation.

Timing synchronization for networks, servers, hubs, routers and switches.

Timing Reference input for various energy metering ICs.

Smart metering, data loggers.

GPS receivers, telematics.

RELATED EUROQUARTZ PRODUCTS

If temperature compensation is not required please consider using Euroquartz HA series 32.768kHz (AT-CUT crystal, µA current

consumption, ±25/±50/±200ppm over commercial or industrial temperature ranges).

If tighter than ±5ppm frequency stability is required, i.e. ±1~±2.5ppm over -40° to +85°C, please consider use of EM572T

32.768kHz TCXO or VEM572T 32.768kHz VCTCO series. (All use AT-Cut crystals, mA current consumption.)
