The sides are intentionally left open to permit cleaning material to freely flow in the package, thus minimizing the accumulation of contaminants during cleaning processes. The internal part of the package must be thoroughly dry before operating. • Pad Function Note 1 Output Enable/Disable When this pad is not connected the oscillator shall operate. When this pad 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. 2 Ground (GND) 3 Output 4 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 S3884 - 32.768K CMOS Clock Oscillator June 2007 Temperature (°C) Reflow Cycle (typical for lead free processing) 260°C Maximum 10 Seconds Maximum 250 215°C±10°C 200 175°C±10°C 150 100 Approximately 50 Seconds 120 to 160 Seconds Allowed rate of temperature change Maximum 4°C per second The part may be reflowed 2 times without degradation.
