TIMING CHARACTERISTICS (continued)

(VCC = +2.25V to +3.0V, C1–C4 = 0.1µF, TA = TMIN to TMAX, unless otherwise noted. Typical values are at VCC = +2.5V,

TA = +25°C.)

Note 2: A transmitter/receiver edge is defined as a transition through the transmitter/receiver input logic thresholds.

Note 3: Transmitter skew is measured at the transmitter zero crosspoints.
