20. PROBLEM DESCRIPTION / DISCUSSION / EFFECT
The EDAC control register electrical performance characteristic parameter tAVCL (Table 1A,
sheet 8 of SMD: 5962-10202) min of 200ns is insufficient for reliable accesses to the EDAC
control register settings. An incorrect test method resulted in inaccurate initial
characterization data.
21. ACTION TAKEN / PLANNED
Aeroflex’s test methodology has been corrected. Device Characterization has been performed
to verify compliance with the increased 400ns minimum specification. Additionally, parameters
tCHAV and tCLAX specifications of 0ns minimum were added to clarify the EDAC control register
sequence.
Aeroflex is working in coordination with DLA Land and Maritime to effect the changes
referenced in this ADEPT to the SMD, which is currently at revision level B.
The proposed list of SMD changes related to parameters tCHAV, tCLAX, and tAVCL are appended to
this GIDEP.
Fielded units are guaranteed by design to meet these parameters, no field returns are planned.
