Arria 10 External PLL Interface Signals
50G Interlaken IP core variations that target an Arria 10 device require an external transceiver PLL to
function correctly in hardware. 50G Interlaken IP core variations that target an Arria V or Stratix V
device include the transceiver PLLs and do not require that you configure any additional PLLs.

Description
tx_serial_clk
Input
NUM_LANES
High-speed clock for Arria 10
transceiver channel, provided from
external TX PLL.
tx_pll_locked
Input
1
PLL-locked indication from external
TX PLL.
tx_pll_powerdown
Output
1
Output signal from the IP core
internal reset controller. The IP core
asserts this signal to tell the external
PLLs to power down.

Arria 10 Transceiver Reconfiguration Interface Signals
The 50G Interlaken IP core Arria 10 transceiver reconfiguration interface allows you to communicate
with Arria 10 hard PCS registers. This interface is available only in variations that target an Arria 10
device. You use this interface to reconfigure the transceiver and to take advantage of built-in transceiver
features that the 50G Interlaken IP Core supports for IP core testing. The interface allows you to address a
single register in a single transceiver channel at one time.
The Arria 10 transceiver reconfiguration interface is a typical 32-bit memory-mapped register port. It
complies with the Avalon Memory-Mapped (Avalon-MM) specification defined in the Avalon Interface
Specifications.
