When this pin is logic low the output will be inhibited (high impedance state.) Recommend connecting this pad to VCC if the oscillator is to be always on. 7 Ground (GND) 8 Output 14 Supply Voltage (VCC) Recommend connecting appropriate power supply bypass capacitors as close as possible. Layout and application information For Optimum Jitter Performance, Pletronics recommends: • a ground plane under the device • no large transient signals (both current and voltage) should be routed under the device • do not layout near a large magnetic field such as a high frequency switching power supply • do not place near piezoelectric buzzers or mechanical fans. www.pletronics.com 425-776-1880 6 P1145-HCM-32.768K CMOS Clock Oscillator July 2007 IMPORTANT NOTICE Pletronics Incorporated (PLE) reserves the right to make corrections, improvements, modifications and other changes to this product at anytime.
