DUAL-CHANNEL 10-GBE SFI-TO-XAUI™ TRANSCEIVER WITH EDC

BCM8727 Functional Block Diagram

• Dual-channel SFI-to-XAUI™ transceiver

• Integrated microcontroller and AGC with a wide dynamic

range

• Supports SFP+ SR, LR, and LRM optical interfaces and up to

15m of direct attached copper

• Programmable amplitude control on 10G serial transmitter

interface

• Standard two-wire Broadcom Serial Interface (BSC) support

for external E2, XFP, SFP, SFP+

• MDIO interface compliant to IEEE802.3ae Clause 45 with

extended indirect address register access

• Support for XFP/XFI interfaces

• Physical Medium Dependent (PMD) interface: serial 10.3125

Gbps CML

• PCS 64B/66B scrambler/descrambler

• XGXS 8B/10B error detection ENDEC

• XAUI link synchronization/deskew

• 4-lane XAUI interface (3.125 Gbps)

• Built-In Self-Test (BIST) on 10G serial and XAUI interfaces

• Power dissipation: 2.4W

• Core supply—1.0V, I/O—3.3V

• Small 19 mm x 19 mm BGA package, 1-mm ball pitch

• Single-reference clock input enables use of low-cost 156.25

MHz oscillator.

• Supports low-cost SFP+ copper twin-ax up to 15m

• LRM mode supports 300m of Multimode Fiber (MMF),

exceeding the IEEE 802.3aq standard.

• PMD transmit preemphasis for flexible placement of Physical

Layer (PHY)

• Support for module present detection and configuring of

BCM8727 accordingly

• Multirate 10 GbE and 1 GbE support for legacy interfaces

• High-density Ethernet Switching and Routing Platforms

• Next-generation Blade Servers

• SFP+ optical SR, LR, and LRM modules
