This paper describes key technologies that enable Stratix IV GT FPGAs to deliver the performance and capabilities necessary to support 40G/100G applications with integrated 11.3 Gbps transceivers. These include the LC-based oscillator and decision-feedback equalization (DFE) at 40 nm for ultra-low jitter FPGA transceivers. Furthermore, the transceiver architecture, including clocking and clock data recovery (CDR) technologies, are highlighted, as well as performance validation results.
