ATCA-9405 Installation and Use (6806800M71G) 66
In addition, CN6880 provides a 10/100/1000 Ethernet MAC-to-PHY interface supporting either
an MII MAC or an RGMIII MAC. The MII links are fully compliant with the IEEE 802.3
specifications, and the RGMII links are fully compliant with the HP RGMII 1.3 specifications.
On ATCA-9405 two DXAUI, two RXAUI, and one RGMII interface are implemented.
3.8.1 Front Panel Interface
The RGMII interface is connected to a 10/100/1000Base-T port at the front panel. The physical
interface is implemented using Marvell 88E1512 Single Port Gigabit Ethernet Transceiver and
an RJ45 connector with integrated magnetics.
3.8.2 Base and Fabric Interface
The SGMII interface (using QLM0 SerDes module) is connected to the Ethernet Switch and
provides a Gigabit Ethernet interface to the control plane (Base Interface).
The two DXAUI interfaces (using QLM2 and QLM4 SerDes module) are connected to the
Ethernet Switch and provide a 2x20G Ethernet interface to the data plane (Fabric Interface).
The two RXAUI interfaces (using QLM0 SerDes module) are connected to the Ethernet Switch
and provide a 20 Gigabit Ethernet interface to the data plane (FI).
3.9 Interlaken Interface
The Interlaken interface unit provides a narrow, high-speed, channelized packet interface using
the scalable Interlaken protocol. It conforms to the Interlaken Protocol Definition V1.2 and the
Interlaken Look-Aside Protocol Definition V1.1. Interlaken combines the channelization,
programmable burst sizes, and per-channel backpressure features of the SPI4.2 protocol with
the long-reach and reduced pin count of the XAUI protocol, and it offers the ability to tailor the
design to the interface capacity of the application.
The Interlaken interface unit supports SerDes lanes running at up to 6.25 Gbps, two
links/interfaces, and x8, x4, x2, and x1 configurations. On ATCA-9405 the Interlaken interface
(using QLM1 SerDes module) is used for interconnection between the two Packet Processors
(when ATCA-9405-ILK-MODULE is assembled).
