Chapter 13: Arria V Transceiver Native PHY IP Core 13–15
Interfaces
November 2012 Altera Corporation Altera Transceiver PHY IP Core
User Guide
Interfaces
The Native PHY includes several interfaces that are common to all parameterizations.
The Native PHY allows you to enable ports, even for disabled blocks to facilitate
dynamic reconfiguration.
The Native PHY uses the following prefixes for port names:
Standard PCS ports—
tx_std
,
rx_std
PMA ports—
tx_pma
,
rx_pma
The port descriptions use the following variables to represent parameters:
<n>—The number of lanes
<p>—The number of PLLs
<r>—the number of CDR references clocks selected
Common Interface Ports
Common interface consists of reset, clock signals, serial interface ports, control and
status ports, parallel data ports, PMA ports and reconfig interface ports. Table 13–18
describes these ports.
Figure 13–3illustrates these interfaces.
