SEAGATE 1200 SSD PRODUCT MANUAL, REV. A 31
6.3.1 Conducted noise immunity
Noise is specified as a periodic and random distribution of frequencies covering a defined frequency. Maximum allowed
noise values given below are peak-to-peak measurements and apply at the drive power connector.
6.3.2 Power sequencing
The drive does not require power sequencing. The drive protects against inadvertent writing during power-up and down.
6.3.3 Current profiles
The +12V and +5V current profiles for the Seagate 1200 SSD 2.5” drives are shown below.
Figure 1. Current profiles for 800GB standard and 400GB High Endurance models
+3.3v = TBD mv pp from TBD Hz to TBD Mhz
+5v = 250 mV pp from 100 Hz to 20 MHz.
+12v = 450 mV pp from 100 Hz to 100 KHz.
250 mV pp from 100 KHz to 20 MHz.
150 mV pp from 20 MHz to 80 MHz.
