Clock Resource for PLD-Transceiver Interface
For the regional or global clock network to route into the transceiver, a
local route input output (LRIO) channel is required. Each LRIO clock
region has up to eight clock paths and each transceiver block has a
maximum of eight clock paths for connecting with LRIO clocks. These
resources are limited and determine the number of clocks that can be used
between the PLD and transceiver blocks.
LRIO resources available for Stratix II GX devices with different numbers
of transceiver blocks.
