5 x 3.2mm SMD Low Power Oscillator
FEATURES
Micro-miniature 5.0 x 3.2mm package
Frequency Range 370kHz to 50MHz
Low supply current <1.7mA at 1.8V supply
Supply voltage range, 1.8, 2.5V or 3.3 Volts
Tristate function to conserve power
Stable and clean CMOS output
DESCRIPTION
XOK53 oscillators are designed for battery operated portable and/or
hand-held consumer electronic devices where small size and low
supply current consumption is essential. A XOK53 at 27MHz and 1.8
Volts supply consumes less than 1.7mA in operating mode and less
than 2 µA in disabled mode. XOK53 phase noise is -130dBc/Hz at
10kHz offset. The oscillator is available with supply voltage 1.8, 2.5 or
3.3 Volts.
