O
HSTL O
All unused HSTL outputs can be left floating. We recommend
that there is no trace attached. Both sides of the differential
output pair should either be left floating or terminated.
C
The CLK /nCLK accepts differential input signals of both V
and V
to 3D show interface examples for the ICS85211I-01 clock input

termination requirement. For example in Figure 3, the input
termination applies for HSTL drivers. If you are using an HSTL
driver from another vendor, use their termination
recommendation.
