Description
The impedance of the pull up (PRU) and pull down (PRD) on the AMB DDR Outputs is relatedto RB
12
& RC
12
as follows:
RC
12
= RB
12
= 5.3125 *Desired Output Impedance
A resistor value of 82
Ω
results in an impedance at a JEDEC nomnal value of 15
Ω
. The user can adjust
these value to optimze the DDR output impedance for a DIMMraw card configuration.
