4.6.3 eUSB Flash Module
The 2mm eUSB header is designed to support industry-standard low-profile eUSB modules.
The ATCA-F140 has a 2GB SG9ED52M2GGDNEMR module from Smart Modular. This is a
custom module developed by Smart Modular for Artesyn which includes 30u" of gold over 50u"
of nickel plating on the connector in order to meet NEBS requirements. This module is capable
of sustained read speeds up to 35MB/sec and write speeds up to 23MB/sec.
4.7 Base Channel Interface
The ATCA-F140 uses Broadcom BCM56334 as its base channel interface. It provides 24
10/100/1000 Mbps ports and four 10G stacking ports. It supports advanced Layer2 switching,
L3 routing, ACL and key carrier protocols. The PCI Express 1x interface of the Broadcom
BCM56334 is attached to one of the PCI Express ports of the integrated processor to provide
service processor configuration and management capability to switch.
Some of the 1GbE SGMII ports from the BCM56334 have the option of being routed through
muxes to two different destinations as seen in the block diagram above. The ATCA-F140 board
uses 2 channel or 4 channel high speed broadband 2:1 multiplexer/demultiplexer switches to
perform this function. The select pins for these mux/demux switches are routed to the FGPA.
Through the P2020 local bus interface, the service processor can program registers in the
FPGA to route the SGMII ports to the desired destination.
4.7.1 Base Channel PHYs
The ATCA-F140 uses two Broadcom BCM54680 octal PHYs, two BCM54616S PHYs, and a
BCM8727 PHY for the base channel. Each BCM54680 supports eight SGMII channels to the
BCM56334 and provides the physical layer functions for the 10/100/1000Base-T connections
and 10/100Base-TX connections to the backplane. The BCM54616S is a single PHY that
supports an SGMII channel to the BCM56334 and provides the physical layer functions for a
10/100/1000Base-T connection to the backplane.
The BCM8727 PHY is a two port XAUI to 10Gb SFI PHY that provides the interface between two
of the Base Switch 10GbE stacking ports and the front panel SFP+ modules. The BCM8727
requires an external SPI flash device of at least 16 Kbytes to load microcode into the device. An
AT25128B or equivalent SPI flash device will be used for this purpose.
