AC ELECTRICAL CHARACTERISTICS (continued)
over operating free-air temperature range (unless otherwise noted)
Typical operating condition is at V_CC = 3.3 V and T_A = 25°C.

TEST CONDITIONS
V_AS
LOS assert threshold voltage
K28.5 pattern at 6.25 Gbps over a

(2) This specification is for 0°C to 85°C. Depending on the interconnect line length and performance, the bit pattern, and the data rate, the
assert and de-assert threshold voltage levels vary. For more information, see the Typical Characteristics section.
