Notes

1. “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 ΔVOD1.

3. All typicals are given for: VCC = +3.3V, TA = +25°C.

4. The PI90LV047A is a current mode device and only functions within datasheet specifications when a resistive load is applied to the driver

outputs typical range is (90 ohms to 110 ohms).

5. tSKD1 |tPHLD – tPLHD | 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 within 5°C 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

|Max – Min| differential propagation delay.

9. Generator waveform for all tests unless otherwise specified: f = 1 MHz, ZO = 50 ohms, tr ≤1 ns, and tf ≤1ns.

10. ESD Ratings:

HBM (1.5 kohms, 100pF) ≥10kV

EIAJ (0 ohm, 200pF) ≥1200V

11. Output short circuit current (IOS) is specified as magnitude only, minus sign indicates direction only.

12. CL includes probe and jig capacitance.

13. All input voltages are for one channel unless otherwise specified. Other inputs are set to GND.

14. f MAX generator input conditions: tr = tf <1ns (0% to 100%), 50% duty cycle, 0V to 3V.

Output Criteria: duty cycle = 45%/55%, VOD >250mV, all channels switching.
