This test load circuit is used to measure all switching characteristics provided in this document.
A.
Input requirements in this data sheet are tested with an input slew rate of < 4 Volts per nanosecond (4 V/ns) at the
device pin.
The data sheet provides timing at the device pin. For output timing analysis, the tester pin electronics and its
transmission line effects must be taken into account. A transmission line with a delay of 2 ns or longer can be used to
produce the desired transmission line effect. The transmission line is intended as a load only. It is not necessary to
add or subtract the transmission line delay (2 ns or longer) from the data sheet timing.
B.

This also applies to the X1 pin if a 1.8-V oscillator is used.
Lower LSPCLK and HSPCLK will reduce device power consumption.
This is the default reset value if SYSCLKOUT = 100 MHz.
