EM7604-C7

EM MICROELECTRONIC - MARIN SA EM7604-C7 Low Power Crystal Oscillator 32.768 kHz Description The EM7604-C7 is a very low power crystal oscillator, which consists of a 32.768 kHz tuning fork crystal and an advanced CMOS oscillator circuit assembled in the same ultra small, cost-effective SMD ceramic package C7. No external components are required. It combines excellent oscillator stability with a very low power consumption of typ. 300nA, guaranteed over a very wide supply voltage and temperature range. The output frequency is synchronized with signal on input Clock Enable CLKEN. The frequency output CLKOUT is enabled by connecting Clock Enable pin CLKEN to VDD. Connecting CLKEN to Vss, disables the frequency and the output CLKOUT is at Low State. Typical Applications  General purpose clock generator for digital systems  Clock drivers for Real Time Clocks  Timekeeping in network servers and computers  Electricity, gas and water metering  Portable field communication  Mobile phone Features  Very low power consumption typ. 300nA  Wide supply voltage range: 1.2V to 5.5V  Operating temperature range: -10°C to +85°C.  Very tight frequency tolerances: ± 20ppm  Excellent oscillator stability: 0.2 ppm/V  Synchronised output after Enable/Disable  Low aging  High shock and vibration resistant  All-in-one-package solution  Miniature ceramic package for SMD mounting, package height 1.0mm  100% lead free, RoHS - compliant Block Diagram 3 CLKEN VDD 4 REGULATION OSCILLA...
