BBT3420
FN7481.1
Quad 2.488-3.1875Gbps/Channel Transceiver
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) 2.4883.1875Gbps 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 25Ω series output terminations (XGMII side)
• Standard 0.18µm 1.8V CMOS technology
• 3.3V tolerant I/O
