This requirement is best met by using a PE99xxDV oscillator and a -3.3V regulator and operating the device from the 5.0V supply. PECL, LVDS, OCXO Page 1 - 7 Pl tronics,.

Pletronics recommends laying out for the larger 'B package' with pads long enough to accept the smaller 5 x 7mm device. This permits the best option for alternate sources of device. Pletronics also recommends connecting Pin 1 and Pin 2 together on the models with Q & QN OUT on pins 4 & 5. This allows having E/D on either pin 1 or pin 2. MULTI LAYER BYPASS For Optimum Jitter Performance, Pletronics recommends: A ground plane under the device with any other signals below the ground plane Minimize other RF signals near 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 mechancial fans Reflow Cycle for lead free processing 260°C max 10 Seconds max Temperature °C 250 200 175°C ± 10°C 120 to 160 Seconds 150 215°C ± 10°C 50 Seconds 100 T Rise= 4 Degree/second max Mar 2004 Pl tronics, Inc.

Direct circuit connection is not valid. ECL Mixed supply voltages are allowed. No translation is necessary. (ECL is returned to the most positive supply and this is common to all circuits) LVDS Mixed supply voltages are allowed. LVDS signal levels are power supply independent. 3.3 V LVDS oscillators properly interface 2.5 V Logic Arrays for example. Mar 2004 6A Pl tronics, Inc.
