R EM MICROELECTRONIC - MARIN SA EM1564 Low Power Crystal Oscillator 32.768 kHz Description Features The EM1564 is a very low power crystal oscillator, which consists of a 32.768 kHz tuning fork crystal and an advanced CMOS circuit assembled in the same very small SMD ceramic package. Very low power consumption, as low as 300nA, is guaranteed over a very wide supply voltage and temperature ranges. The EM1564 is a completely lead free product. All-in-one-package solution Miniature ceramic package for SMD mounting Package height 1.2mm Very low power consumption typ. 300nA Very tight frequency tolerance Excellent oscillator stability: 0.2 ppm/V Wide supply voltage range: 1.2V to 5.5V Operating temperature range: -40°C to +85°C On request extended temperature range: -40°C to +125°C Low aging High shock and vibration resistant 100% lead free, RoHS - compliant Applications General purpose clock generator for digital systems Clock drivers for Real Time Clocks Timekeeping in network servers and computers Data logger Electricity, gas and water metering Portable field communication Mobile phone Block Diagram VDD 1 REGULATION OSCILLATOR Fig. 1 OE 10 OUTPUT CONTROL 5 OUT 6 VSS Fig. 2 Pin Connection Top View Pin Connection 1 VDD Positive Supply Voltage 5 OUT Frequency Output 6 VSS Negative Supply Voltage 10 OE Output Enable Pins 2, 3, 4, 7, 8, 9 are not connected Copyright © 2006, EM Microelectronic-Marin SA 1 www.emmicroelectronic.com R EM1564 Absolute Maximum Ratings Parameter Voltage at VDD to VSS Minimum voltage at OE Maximum voltage at OE Storage temperature range Maximum soldering Handling Procedures This device has built-in protection against high static voltages or electric fields; however, anti-static precautions must be taken as for any other CMOS component. Unless otherwise specified, proper operation can only occur when all terminal voltages are kept within the voltage range. Unused inputs must always be tied to a defined logic voltage level.
