FB-DIMM Electrical Timing Specifications
The FB-DIMM Channel link electrical interface is more completely described in the High
Speed Differential Point-to-Point Link at 1.5V for Fully Buffered DIMM specification.
Refer to this document for recommended operating conditions.
Table 4-5 contains the FB-DIMM electrical timing specifications.
Notes:
1.
Defined in FB-DIMM Architecture and Protocol Spec
2.
Clocks defined as core clocks = 2x SCLK input
Note:
1.
tRESAMPLE is the delay from the southbound input to the southbound output, or the northbound input to
the northbound output when in resample mode, measured from the center of the data eye.
2.
tRESYNC is the delay from the southbound input to the southbound output, or the northbound input to the
northbound output when in resync mode, measured from the center of the data eye.
