PARAMETER
Supply voltage to reach 90% of final value in less than 100µs, but not less than 10µs. Power-on delay interval measured
from the 50% level of the final voltage at the filter’s device side to 50% level of final current. The supply is to remain at or
above 3V for at least 100ms. Only one full-scale transition is permitted during this interval. Aberrations on the transition are
limited to less than 100mV.
IN+ and IN- are single-ended, 50Ω terminations to (V
Load is 50Ω ±1% at each side and the pattern is 0000011111 or equivalent pattern at 2.5Gbps.
Guaranteed by design and characterization.
PE1 = PE0 = logic-high (maximum preemphasis), load is 50Ω ±1% at each side. The pattern is 11001100 (50% edge den-
sity) at 10Gbps. AC common-mode output is computed as:

Using 0000011111 or equivalent pattern at 2.5Gbps. PE0 = PE1 = logic-low for minimum preemphasis. Measured within
2in of the output pins with Rogers 4350 dielectric, or equivalent, and ≥ 10-mil line width. For transition time, the 0% refer-
ence is the steady state level after four zeros, just before the transition, and the 100% reference level is the steady state
level after four consecutive logic ones.
Pattern is 0000011111 or equivalent pattern at 10Gbps and 100mV
PE1 = logic-low for minimum preemphasis. Signal transition time is controlled by the 4th-order BT filter (7.5GHz band-
width) or equivalent. See Figure 3 for setup.
Test pattern (464 bits): 100 zeros, 1010, PRBS7, 100 ones, 0101, PRBS7.
Input range selection is IN_LEV = logic-high for FR-4 input equalization. Cables are unequalized, Amphenol Spectra-Strip
(160-2499-997) 24 AWG or equivalent. Residual deterministic jitter is the difference between the source jitter at point A
and the load jitter point D in Figure 2. The deterministic jitter (DJ) at the output of the transmission line must be from media
induced loss and not from clock source modulation. DJ is measured at point D of Figure 2.
