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.
