EURO QUARTZ XOK91 Series Oscillators 7 x 5mm Low Power Oscillator 250kHz to 50.0MHz FEATURES Industry-standard 7.0mm x 5.0mm package Frequency Range 250kHz to 50MHz Low supply current <1.7mA at 1.8V supply Supply voltage range, 1.8V, 2.5V or 3.3Volts Tristate function to conserve power Available over 'MIL' temperature range -55°~+105°C DESCRIPTION XOK91 oscillators are ideal for battery operated portable or handheld consumer electronic devices where small size and low supply current consumption is essential. A XOK91 oscillator at 27MHz and 1.8 Volts supply consumes less than 1.7mA in operating mode and less than 2 micro Amps in disabled mode. The oscillator is available with supply voltage 1.8, 2.5 or 3.3 Volts.
