TIDA-00234

Dual-channel XAUI to SFI reference design for systems with two or more SFP+ optical ports

TIDA-00234

Design files

Overview

The TIDA-00234 XAUI to SFI reference design is intended for Enterprise and Service Provider Networking applications like Ethernet Switches and Routers that implement multiple 10G Ethernet compliant Optical (SFP+) ports. This reference design features the TLK10232 device which is the most compact Dual-channel XAUI-to-SFI Transceiver with the lowest power consumption in its category. This reference design allows access to the high-speed signals (up to 10Gbps) generated by the TLK10232 via SMA connectors or an SFP+ Module via the SFP+ optical module cage. Also, featured is the CDCM6208 device that can provide extremely low-jitter Clock input to the TLK10232 in customer systems that do not have one available (or does not meet the jitter requirement of the system).

Features

Dual Channel XAUI to SFI reference design which includes SFP+ optical module cage to access high speed signals (up to 10Gbps)
Supports flexible clocking schemes including externally-jitter-cleaned clock recovered from the high-speed side
Features TLK10232 which is the only Dual-channel XAUI-to-SFI Transceiver with Crosspoint capability in addition to:
- Smallest footprint (13x13mm) within its class of devices and
- Lowest power consumption per channel (800mW Nominal/Ch)
