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 4 5 6 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 (see LV76D for E/D on pad 1) 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 www.pletronics.com 425-776-1880 6 LV76D / LV78D Series 2.5 V LVDS Clock Oscillators January 2008 Mechanical (obsolete version): The cover is no longer being supplied over this part. This part is made with a hermetically sealed LV77xxDW series oscillator. This part is now exposed. The cover has been deleted, the cover was causing problems with the newer high temperature RoHS lead free processes. The cover purpose was only cosmetic. All parts with 2008 date codes will be made in the new fashion. There is no change in electrical properties. Pletronics does recommend that all designs should transition to the LV77xxDW ceramic part.
