i'm confuse about this power consumption.
there are exist that power consumption table in the datasheet (11.5 current consumption)
but it is difference SVR & LVR electrical specifications written(184.108.40.206 & 220.127.116.11)
and what means about SVR's PWM mode & PFM mode?
nowhere explain about that in the datasheet
Thank you for the post. Can you help clarify what is the difference you mentioned as table 11.5 refers to current consumption while the table 18.104.22.168 and 22.214.171.124 refers to electrical performance of the 1.0V SVR when using the components specified
in section Section 11.9.1 and electrical performance of the 1.8V LVR using the components specified in section Section 11.9.2.
Where did you see the PWM and PFM mode? PWM refers to Pulse Width Modulation while PFM refers to Pulse-frequency modulation
in the I350 datasheet Revision 2.4
126.96.36.199 section written about load current
The ampere of 4.0A @ PWM mode in 1.0V and 600mA in 1.8V
it is some different i mentioned above table.
which one i take?
Can you help sent the screenshot of the Table you refer to and encircle or highlight the difference.
What i can see is Table 11.5 contains the power consumption page 923 (see attached)
For Table 188.8.131.52 (pls refer to attached file), where is 600m in 1.8V?
here it is 600mA load current @ 1.8V
now i attention about current consumption of each 4port copper & optic
and.. can i control PWM / PFM mode @ I350?
What you refer to are different since Table 22 refers to LVR DC specification while 11.6.91. refers to SVR specification.
Can you help clarify about the control of pwm and pfm mode of i350?
i just ask you about PWM & PFM in that table.
nowhere explain about PWM & PFM in the datasheet, it is suddenly appear in the table
is it possible the configuration of PWM & PFM at I350?
1. 1.0V x 4A + 1.8V x 600mA = 5.08W
2. 4port 1000copper with SVR&LVR = 4.372W
3. 4port 1000fiber with SVR&LVR = 2.938W
which one i refer?
Thank you for the reply. In order to better assist you, are you asking if how do we come up with the value of 4.272W and 2.938W? Are you requesting the formula?
Please help clarify.
No, i just asking you.
which one i refer?
the sum of each SVR and LVR power is 5.08W, but 1000copper with SVR and LVR is 4.372W.
what is the difference?
now i'm in H/W design step, so i need predicted power consumption value.
i don't need formula. just inform me please.
if i design 1G copper or 1G optic, just refer the power consumption table?(4.372Watt, 2.938Watt)
And why there are appear PWM, PFM word?
please identify essential of question
If you are designing the NIC, you can refer to the power consumption table at the data sheet specification but for more detail inquiry about designing , please visit our Research and design center at http://www.intel.com/content/www/us/en/design/resource-design-center.html
