separate the transmitter and receiver in your design, the Quartus II
software merges the fast PLLs when appropriate and gives you the
following message:
Receiver fast PLL <lvds_rx pll name> and transmitter fast PLL
<lvds_tx pll name> are merged together
The Quartus II software gives the following message when it cannot
merge the fast PLLs for the LVDS transmitter and receiver pair in the
design:
tx_outclock Resource
You can use either the global or regional clock for the tx_outclock
signal. If you select Auto in the Quartus II software, the tool uses any
available lines.
SERDES Bypass Mode
You can bypass the SERDES block if your data rate is less than 624 Mbps,
and you must bypass the SERDES block for the
Since you cannot route the fast PLL output to an output pin, you must
create additional DDR I/O circuitry for the transmitter clock output. To
