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 No connect There is no internal connection to this pad 2 Output Enable/Disable When this pad is not connected the oscillator shall operate. When this pad is <0.30 volts, the output will be inhibited (high impedance state.) Recommend connecting this pad to VCC if the oscillator is to be always on. 3 Ground (GND) 4 Output 5 Output* 6 Supply Voltage (VCC) www.pletronics.com Both outputs must be terminated and biased for proper operation. The ideal termination is 50 ohms connected to 2.0V below the Supply Voltage. Recommend connecting appropriate power supply bypass capacitors as close as possible. 425-776-1880 6 PE78D Series 3.3 V PECL Clock Oscillators January 2008 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 The part may be reflowed 2 times without degradation.
