Electrical Specifications
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. The V
TT
referred to in these specifications refers to instantaneous V
TT
.
3. Refer to the processor I/O Buffer Models for I/V characteristics.
4. For V
IN
between 0 V and V
TT
. Measured when the driver is tristated.
5. V
IH
and V
OH
may experience excursions above V
TT
. However, input signal drivers must comply with the
signal quality specifications.
6. COMP resistance must be provided on the system board with 1% resistors. COMP resistors are to V
SS
.
7. R
SYS_TERM
is the system termination on the signal.
