There is no specific device V
CC
supply voltage requirement for SSTL-1.8 compliance. However under all conditions V
CCQ
must be less than or equal to V
CC
.
1. The value of V
REF
may be selected by the user to provide optimum noise margin in the system. Typically the value of V
REF
isexpected to be about 0.5 x V
CCQ
of the transmitting
device and V
REF
is expected to track variations in V
CCQ
.
2. Peak to peak AC noise on V
REF
may not exceed ±2% V
REF
(DC).
3. V
TT
of transmitting device must track V
REF
of receiving device.
4. AC parameters are measured with V
CC
, V
CCQ
and V
CCDL
tied together.
