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.

·
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.)
