Running PRBS 2
Measured with a clock-like pattern at 100 MHz,
between 20% and 80% of the differential output
voltage. Pre-emphasis disabled.
Transition time is measured with fixture as shown
in Figure 5, adjusted to reflect the transition time at
the output pins.
Measured at 50% differential voltage from input to
output.
|t
Difference in propagation delay among data paths
in the same device.
Difference in propagation delay between the same
output from devices operating under identical
condition.
Measured from V
loopback control to 50% of the valid differential
output.
See Figure 5 for test circuit.
Alternating-1-0 pattern.
Pre-emphasis disabled.
