Non-GTL+ Signal Quality Specifications 
Signals driven to the mobile Intel Celeron processor should meet signal quality specifications to 
ensure that the processor reads data properly and that incoming signals do not affect the long-term 
reliability of the processor. Unlike previous generations of mobile processors, the mobile Intel 
Celeron processor uses GTL+ buffers for non-GTL+ signals. The input and output paths of the 
buffers have been slowed down to match the requirements for the non-GTL+ signals. The signal 
quality specifications for the non-GTL+ signals are identical to the GTL+ signal quality 
specifications except that they are relative to V
CMOSREF
 rather than V
REF
OVERSHOOT_CHECKER can be used to verify non-GTL+ signal compliance with the signal 
overshoot and undershoot tolerance. The tolerances listed in Table 26 are conservative. Signals 
that exceed these tolerances may still meet the processor overshoot and undershoot tolerance if the 
OVERSHOOT_CHECKER tool says that they pass.
