All minimum and maximum specifications are 100% production tested except driver dynamic output current and
driver/comparator propagation delays, which are guaranteed by design. All specifications are with DUT_ and PMU_ elec-
trically isolated, unless otherwise noted.
Nominal target value is 49.5Ω. Contact factory for alternate trim selections within the 45Ω to 55Ω range.
Measured at 1.5V, relative to a straight line through 0 and 3V.
Measured at end points, relative to a straight line through 0 and 3V.
DUT_ is terminated with 50Ω to ground, V
RCV_ logic levels are V
Undershoot is any reflection of the signal back towards its starting voltage after it has reached 90% of its swing. Preshoot
is any aberration in the signal before it reaches 10% of its swing.
At the minimum voltage swing, undershoot is less than 20%. DHV_ and DLV_ references are adjusted to result in the
specified swing.
At this pulse width, the output reaches at least 90% of its nominal (DC) amplitude. The pulse width is measured at DATA_.
With the exception of offset and gain/CMRR tests, reference input values are calibrated for offset and gain.
