Dual 10GE Serial-to-XAUI PHY for SFP+ and Serial Backplane

The QT2225 is a dual-port fully integrated 9.95-10.52 Gbps transceiver with adaptive Electronic Dispersion Compensation (EDC). The device provides a high performance interface between a MAC or switch device and copper media including Direct Attach cable and 10GBASE-KR backplanes. The data rate is switchable to 1.25 Gbps, allowing dual 1000BASE-KX / 10GBASE-KR support on a single backplane. It can also interface to optical media including SFP+, SFP and XFP modules. When designing for SFP+ applications, customers can generate one dual-rate design that supports SFP+ modules (10GBASE-R) and SFP modules (1000BASE-X), as well as Twinax cable, providing maximum medium flexibility. In the receive direction the device uses a sophisticated EDC engine that continuously adapts itself to the channel characteristics providing an optimum level of performance regardless of environmental conditions.
