3. AC & DC Operating Conditons
3.1 DC Operating Conditions
3.1.1 Recommended DC Operating Conditions (SSTL_1.8)
3.1.2 ODT DC electrical characteristics
Rtt effective impedance value for EMRS(A6,A2)=0,1; 75 ohm
Rtt effective impedance value for EMRS(A6,A2)=1,0; 150 ohm
Rtt effective impedance value for EMRS(A6,A2)=1,1; 50 ohm
Deviation of VM with respect to VDDQ/2
Note:
1. Test condition for Rtt measurements
Measurement Definition for Rtt(eff): Apply V
(ac)) and I(V
Measurement Definition for VM : Measurement Voltage at test pin(mid point) with no load.
1. Min. Typ. and Max. values increase by 100mV for C3(DDR2-533 3-3-3) speed option.
2. VDDQ tracks with VDD,VDDL tracks with VDD. AC parameters are measured with VDD,VDDQ and VDD.
3. The value of VREF may be selected by the user to provide optimum noise margin in the system. Typically the
4. Peak to peak ac noise on VREF may not exceed +/-2% VREF (dc).
5. VTT of transmitting device must track VREF of receiving device.
