1.8 V conﬁgurable registered buffer for DDR2-800 RDIMM applications

11.2 Output slew rate measurement

VDD = 1.8 V ± 0.1 V.

All input pulses are supplied by generators having the following characteristics:

PRR

≤ 10 MHz; Z

0 =50 Ω; input slew rate=1V/ns ± 20 %, unless otherwise speciﬁed.

(1) CL includes probe and jig capacitance.
