7 x 5mm Low Power Consumption Clock Oscillator
XOK91 oscillators are ideal for battery operated portable or hand-
held consumer electronic devices where small size and low supply
current consumption is essential. A XOK53 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 at 1.8, 2.5 or 3.3 Volts.
Industry-standard 7.0mm x 5.0mm package
Frequency Range 10MHz 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
