"Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices should be operated at these limits. The table of "Electrical Characteristics" specifies conditions of device operation. 2. Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground except: VOD1 and VOD1. 3. All typicals are given for: VCC = +3.3V, TA = +25C. 4. The PI90LV/LVB3487 and PI90LV/LVB9638 are current mode devices and only functions within datasheet specifications when a resistive load is applied to the driver outputs typical range is 90 ohms to 110 ohms for PI90LVxxxx and 47 ohms to 55 ohms for PI90LVBxxxx. 5. tSKD1, ItPHLD - tPLHDI is the magnitude difference in differential propagation delay time between the positive going edge and the negative going edge of the same channel. 6. tSKD2 is the Differential Channel-to-Channel Skew of any event on the same device. 7. tSKD3, Differential Part-to-Part Skew, is defined as the difference between the minimum and maximum specified differential propagation delays. This specification applies to devices at the same VCC and with 5C of each other within the operating temperature range. 8. tSKD4, Part-to-Part Skew, is the differential Channel-to-Channel skew of any event between devices. This specification applies to devices over recommended operating temperature and voltage ranges, and across process distribution. tSKD4 is defined as I Max - Min I differential propagation delay. 9. Generator waveform for all tests unless otherwise specified: f = 1 MHz, ZO = 50 ohms, tr 1ns, and tf 1ns. 10. Output short circuit current (IOS) is specified as magnitude only, minus sign indicates direction only. 11. CL includes probe and jig capacitance. 12. All input voltages are for one channel unless otherwise specified. Other inputs are set to GND. 13. fMAX generator input conditions: tR = tF < 1ns, (0% to 100%), 50% duty cycle, 0V to 3V.
