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) The outputs must be terminated, 100 ohms between the outputs is the ideal termination. 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 on both input pads 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 LV55D Series 2.5 V LVDS Clock Oscillators November 2007 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 The part may be reflowed 2 times without degradation.
