When this pin is logic low the output will be inhibited (high impedance state.) Recommend connecting this pin to VCC if the oscillator is to be always on. 2 3 4 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 SM77M Series 5.0 V CMOS Clock Oscillators Feb 2008 Reflow Cycle (typical for lead free processing) 260°C Maximum 10 Seconds Maximum 215°C±10°C 175°C±10°C Temperature (°C) 250 200 150 100 120 to 160 Seconds Approximately 50 Seconds Allowed rate of temperature change Maximum 4°C per second The part may be reflowed 2 times without degradation.
