EM7604
Low Power Crystal Oscillator Circuit 32.768 kHz
Description
EM7604 is an advanced low power CMOS circuit intended to be used together with a 32.768 kHz tuning fork crystal as a low frequency clock oscillator. Except the crystal, no other external components are required. The device combines excellent oscillator stability with very low power consumption. It is guaranteed over a very wide supply voltage and temperature range. In order to achieve a high frequency accuracy, the matched crystals should have a ± 20ppm tolerance or tighter. 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.
