QT2025

10GE Serial to XAUI PHY for 10GBASE-LRM, LR, SR, 10GBASE-KR

The QT2025 is a fully integrated 9.95-10.52 Gbps transceiver with fully adaptive Electronic Dispersion Compensation (EDC). The device provides a high performance interface between a MAC or switch device and copper media including Twinax 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 design using Auto-Negotiation for rate selection. It can also interface to optical media including SFP+, SFP and XFP modules or reside inside a XENPAK or X2 module. 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.
