NOTES:
1. There are two different terminations that are used with the following tests. The loadboard in Figure 2. IBIS Model Output Load is used to measure
the input and output differential-pair cross voltage only. The loadboard in Figure 3. Output Load Test Circuit 1 is used to measure all other tests.
For consistency, equal length cables must be used.
2. Static Phase offset does not include Jitter.
3. Period Jitter and Half-Period Jitter specifications are separate specifications that must be met independently of each other.
4. The Output Slew Rate is determined form the IBIS model into the load shown in Figure 4. Output Load Test Circuit 2. It is measured single ended.
5. To eliminate the impact of input slew rates on static phase offset, the input slew rates of Reference Clock Input CK, CK and Feedback Clock
Input FBIN, FBIN are recommended to be nearly equal. The 2.5 V/ns slew rates are shown as a recommended target. Compliance with these
Nom values is not mandatory if it can be adequately demonstrated that alternative characteristics meet the requirements of the registered DDR2
DIMM application.
