POS-PHY Level 2 and 3 Compiler

from Altera Corporation

Features

Link-layer or PHY-layer POS-PHY interfaces
Bridges between different POS-PHY interfaces
Single-PHY (SPHY) or up to 8-channel multi-PHY (MPHY) operation, with configurable FIFO buffers
Atlantic^TM interface allows a consistent interface between all Altera^® cell and packet MegaCore^® functions

High Performance

Supports traffic up to a rate of 3.2 Gbps in POS-PHYLevel 3 (OC-48) and 832 Mbps in POS-PHY Level 2
Up to 350-MHz intellectual property (IP) core frequency

General Description

The POS-PHY Level 2 and 3 compiler generates MegaCore functions for use in link-layer or PHY devices that transfer data to and from packet over SONET/synchronous digital hierarchy (SDH) devices using the standard POS-PHY bus. The compiler comprises separately configurable modules, which can be easily combined via the IP Toolbench to generate a highly parameterized module, allowing POS-PHY compliant interfaces (and non-standard interfaces) to be included in custom designs. Figure 1 shows the possible interfaces. Figure 2 shows the possible bridges.

Atlantic Interface

The Atlantic interface allows a consistent interface between all Altera cell and packet MegaCore functions. The Atlantic interface supports a point-to-point connection.

For more information on the Atlantic interface, refer to FS 13: Atlantic Interface.
