Tool/software:
I am configuring a system using DDR3.
To match the DDR3 impedance, I need to set the impedance of the single-ended and differential signals.
According to the AM5708 manual, I can set Imp80 to Imp34Ω by setting "l[2:0] =".
I'm not sure if this setting is common to both single-ended and differential signals, or if it can be set separately.
My understanding is that setting "l[2:0] = 010(Imp48)" will result in an output impedance of Imp48Ω for both single-ended and differential signals.
Or, for example, if I set it to Imp48 (48Ω), is it correct to understand that the single-ended impedance is 48Ω and the differential signal impedance is 96Ω?
I'm in a hurry, so a quick response would be appreciated.
Thank you in advance.
