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. 2 No connect There is no internal connection to this pad 3 Ground (GND) 4 Output 5 Output* 6 Supply Voltage (VCC) 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. Layout and application information Recommend connecting Pad 1 and Pad 2 together to permit the design to accept Enable/Disable input on either pad 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 PE77D Series 2.5 V PECL Clock Oscillators June 2011 Reflow Cycle (typical for lead free processing) 260°C Maximum 10 Seconds Maximum Temperature (°C) 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 3 times without degradation.
