1 Features

? Four channels of transmitter and receiver with serial data

transfer rates of 2.488-3.1875Gbps/channel with full rate

and half-rate operations

? Up to 12.75Gbps data rate at full duplex

? User-controlled dual-speed operation (per channel) 2.488-

3.1875Gbps or 1.244-1.59Gbps

? IEEE 802.3ae-2002 10 GE and 10 GFC compliant

- XAUI, XGMII, and MDC/MDIO interfaces

? XGMII format 10-bit parallel input/output data

- Supports HSTL 1.8V and 2.5V SSTL_2

? Extensive configuration via 802.3-compliant MDC/MDIO

serial interface

? 8bit/10bit Encoding/Decoding per channel with selectable

parallel input/output data sizes

- Support optional 8b/10b encoder/decoder bypass

operation

? Integrated Equalization and Pre-emphasis

? De-skewing and channel-to-channel alignment options

? Low power, 250mW per channel typical

? Meets jitter requirements with significant margin

? Comma detection and synchronization, byte alignment

? Tx/Rx rate matching via IDLE insertion/deletion

? Receive signal detect and 16 levels of transmission

medium equalization

? CML transmit outputs with four levels of pre-emphasis

? Loopback

- Per-channel serial Tx-to-Rx and Rx-to-Tx parallel

internal loopback modes

? Single-ended/differential input Reference clock

? Double Data-Rate (DDR) mode, also optional SDR (Single

Data Rate) on transmitter

? Support both source-centered and source-simultaneous

clocking

? Long Run Length (512 bit) frequency lock ideal for

proprietary encoding schemes Transmit byte clock

schemes

- One Transmit Byte Clock (TBC) for each channel, or

one TBC for all four channels

? Received clock schemes

- Receive data aligned to local reference clock, to

recovered clock for each channel, or to recovered clock

for Channel A only

? Supports Built-In Self Test (BIST) and IEEE 1149.1 JTAG

? On-chip 25? series output terminations (XGMII side)

? Standard 0.18μm 1.8V CMOS technology
