Switching Characteristics (Continued)
Note 8: tSKD2 or differential channel-to-channel skew is defined as the magnitude difference in the differential propagation delays between two driver channels on
the same device.
Note 9: tSKD3 or differential part-to-part skew is defined as |tPLHD Max −tPLHD Min|or|tPHLD Max −tPHLD Min|. It is the difference between the minimum and maximum
specified differential propagation delays. This specification applies to devices at the same VDD and within 5˚C of each other within the operating temperature range.
Note 10: tSK1 or pulse skew is defined as |tPHL −tPLH|. It is the magnitude difference in the propagation delays between the positive going edge and the negative
going edge of the same receiver channel.
Note 11: tSK2 or channel-to-channel skew is defined as the magnitude difference in the propagation delays between two receiver channels on the same device.
Note 12: tSK3 or part-to-part skew is defined as |tPLH Max −tPLH Min|or|tPHL Max −tPHL Min|. It is the difference between the minimum and maximum specified
propagation delays. This specification applies to devices at the same VDD and within 5˚C of each other within the operating temperature range.
Note 13: Generator waveform for all tests unless otherwise specified:f=1 MHz, ZO =50 Ω,tr ≤ 1 ns, and tf ≤ 1 ns.
Note 14: Output short circuit current (IOS) is specified as magnitude only, minus sign indicates direction only.
Note 15: All input voltages are for one channel unless otherwise specified. Other inputs are set to GND.
Note 16: fMAX generator input conditions: tr =tf < 1 ns (0% to 100%), 50% duty cycle,0Vto3V. Output Criteria: duty cycle = 45%/55%, VOD > 250 mV, all channels
switching.
Note 17: fMAX generator input conditions: tr =tf < 1 ns (0% to 100%), 50% duty cycle, VID = 200 mV, VCM = 1.2 V . Output Criteria: duty cycle = 45%/55%, VOH
> 2.7 V, V
OL < 0.25 V, all channels switching.
