Conducted noise
Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on the +5 volt line.
Using 5-volt power, the drive is expected to operate with a maximum of
100 mV peak-to-peak square-wave injected noise at up to 20 MHz.
2.7.3
Voltage tolerance
Voltage tolerance (including noise):
+5V ± 5%
Note
Equivalent resistance is calculated by dividing the nominal voltage by
the typical RMS read/write current.
