8 Lyrion Series IDE Product Manual, Rev. B
2.7.2 Conducted noise
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.
2.7.3 Voltage tolerance and Maximum current
Voltage tolerance (including noise):
3.3V ± 5%
Maximum Current (peak-to-peak):
500mA
