EURO QUARTZ XOK53 Series Oscillators 5 x 3.2mm SMD Low Power Consumption Clock Oscillator FEATURES · · · · · Micro-miniature 5.0mm x 3.2mm package Frequency Range 16MHz to 50MHz Low supply current <1.7mA at 1.8V supply Supply voltage range, 1.8, 2.5V or 3.3Volts Tristate function to conserve power OUTLINE & DIMENSIONS DESCRIPTION XOK53 oscillators are designed for battery operated portable or hand-held consumer electronic devices where small size and low supply current consumption is mandatory. A XOK53 at 27MHz and 1.8 Volts supply consumes less than 1.7mA in operating mode and less than 2 micro Amps in disabled mode. XOK53 phase noise is 130dBc/Hz at 10kHz offset. The oscillator is available with supply voltage at 1.8, 2.5 or 3.3 Volts.
