Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on 
the +3.3 volt line.

Using 3.3-volt power, the drive is expected to operate with a maximum of 70 mV

peak-to-peak square-wave 

injected noise at up to 20 MHz.

Note. Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write 

current.

Voltage tolerance (including noise):

3.3V ± 5%
