10. Test Load - 12 pF
11. Measured at the receiver.
12. Reference only: Tdv = Max. clock cable delay + Max. data cable delay + Max. data HiZ to output time = 12nS + 35nS + 22 nS = 69nS. Max. clock
cable delay and max. data cable delay are worst case numbers based on electrical simulation.
13. Reference only: Tdv = Max. clock backplane delay + Max. data backplane delay + Max. data HiZ to output time = 26nS + 46nS + 11nS = 83nS. Max.
clock delay and max. data delay are worst case numbers based on electrical simulation.
14. Based on worst case electrical simulation.
15. This range accounts for
Φ
(Phase Correction).
16. Tcell = Max. clock backplane delay + Max. data backplane delay + Max. Tzdo + (Min. Tdiv - Max. Tdv) + Max Tdoz + F = 26nS + 46nS + 11nS +
(102nS - 83nS) + 10nS + 10nS = 122nS. Max. clock delay and max. data delay are worst case numbers based on electrical simulation.
The rise and fall times are determined by the edge rate in V/nS. A maximum edge rate is the fastest rate at which a clock transitions.
10% - 90%. Test Load = 150 pF.
Tc8p Min and Max are under free-run conditions assuming ±32 ppm clock accuracy.
Non-cumulative, Tc8p requirements still need to be met.
Duty Cycle measured at transmitter under no load conditions.
For reference only
Test Load - 200 pF
Measured at the transmitter.
Tdoz and Tzdo apply at every time-slot boundary.
