Notes:
1. Parameters are guaranteed by design and characterization.
2. CL includes probe and jig capacitance.
3. Signal generator conditions for dynamic tests: VOL = 0, VOH = 2.4V, f = 100MHz, 50% duty cycle, RO = 50Ω,
tR ≤ 1ns, tF ≤ 1ns (0 to 100%).
4. tSKD1 is the magnitude difference of differential propagation delay. tSKD1 = |tPHLD - tPLHD|.
5. tSKD2 is the magnitude difference of tPHLD or tPLHD of one channel to the tPHLD or tPLHD of another channel on the same device.
6. tSKD3 is the magnitude difference of any differential propagation delays between devices at the same VCC and within 5°C of each other.
7. tSKD4 is the magnitude difference of any differential propagation delays between devices operating over the rated supply and tempera-
ture ranges.
8. fMAX signal generator conditions: VOL = 0, VOH = 2.4V, 50% duty cycle, RO = 50Ω,
tR ≤ 1ns, tF ≤ 1ns (0 to 100%).
9. Transmitter output criteria: duty cycle = 45 to 55%, VOD ³ 250mV.
10. For optimum performance matched circuits should be used.
