Notes 1. Specifications apply per channel.
2. TPD or Average clock delay is defined as the average delay from finger to finger of all RSL clock nets
(CTM, CTMN, CFM, and CFMN).
3. If the RIMM module meets the following specification, then it is compliant to the specification.
If the RIMM module does not meet these specifications, then the specification can be adjusted by the
“Adjusted

Note N = Number of RDRAM devices installed on the RIMM module.
Z0 = delta Z0% = (MAX. Z0 - MIN. Z0) / (MIN. Z0)
(MAX. Z0 and MIN. Z0 are obtained from the loaded (high impedance) impedance coupons of all RSL layers
on the module.)
