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.

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.)
