Hi, everybody=20
I am designing a PCI video capture card. The main ICs are: Cyclone=20
II (EP2C35F672c6), ADV7181, ADV7123, PCI9054, 128M SDRAM etc. Now I=20
am making a power consumption estimation for this board. I have=20
finished the power requirements estimation for ICs. And I have=20
several questions:=20
First, is the estimation I have made reasonable? (Pls see the table=20
below)=20
FPGA SDRAM ADV7181 ADV7123 PCI9054 MAX3221CDBE4=20
840mW 782mW 547.1mW 97.54mW 920mW 3.6mW=20
Others(resistors,leds...) Total=20
? 3190.24+?=20
Secondly, I made some calculations for the pull-up and termination=20
resistors and LEDS. I find each resistor consumes several mWs, even=20
less than 1 mW and each LED consumes about 20 or 30 mWs when on. Is=20
that reasonable?=20
Finally, I want to receive some good advices on the proportion of=20
the non-IC devices=A1=AF power consumption usually accounts for. And how=20
much power supply margin should I offer for the whole board?=20
Looking forward your help. Thank u very much.=20
