Table 5-8: 100G Interlaken IP Core Arria 10 External PLL Interface Signals

Signal Name Direction Width (Bits) 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 100G 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 100G 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.
