10 GB/S ETHERNET TRANSCEIVER WITH XAUI INTERFACE FOR IEEE 802.3AE PLIANT LAN/MAN APPLICATIONS
WHAT IT GIVES YOU: An array of well-planned, high-performance Features that facilitate the design of 10 Gb/s Ethernet fiber-optic modules. WHAT IT DOES: The QT2020 converts a 10 Gb/s serial data stream into four 3.125 Gb/s serial lanes via the IEEE specified XAUI (10 Gb/s attachment unit interface) data bus. Superior jitter tolerance allows the designer to allocate jitter budget elsewhere in the module design. On-chip clock generation means no need for external VCXOs, so fewer external ponents are required. The QT2020 has an adjustable fiber side output signaling range, which allows a large selection of mercially available laser drivers to be connected directly to the QT2020. Programmable XAUI peaking provides pre-emphasis adjustment to account for channel loss, which broadens the choice of receivers used in the system. The QT2020 exceeds the IEEE and Telcordia GR-253-CORE requirements for receiver jitter tolerance, with the demonstrated ability to successfully recover clock and data in stressed eye testing. Support for the EEPROM interface provides rapid, easy initialization of the device in accordance with the XENPAK Multisource Agreement (MSA). Fully integrated test Features enable quick evaluation and faster time to market. Five loopback modes are available to facilitate lab and system diagnostics. SOME KEY Features
