Note 1:
AC characterization is performed using the circuit in Figure 2 using a PRBS 2
23
- 1 or equivalent pattern.
Note 2:
Specifications at -40°C are guaranteed by design and characterization.
Note 3:
Excluding I

OUT
). V
OUT
is the voltage across the 15
load when IN+
is high.
Note 5:
The minimum required voltage at the OUT+ and OUT- pins is +0.75V.
Note 6:
Guaranteed by design and characterization.
Note 7:
Tested with 00001111 pattern at 2.7Gbps.
Note 8:
DJ includes pulse-width distortion (PWD).
