5MHz-35MHz Low Power Crystal Oscillator - TSMC 0.18µ

The OT0210bj is a flexible crystal oscillator for the TSMC 0.18µ CMOS processes. It is designed to operate with standard AT cut crystals. This cell does not include primary ESD protection and is designed to be used with standard ESD pads. Current adjustment is provided to optimize power and accommodate crystal characteristics over the frequency range.
