 Examining Stratix card ability of GX (protocols and parameters).  Testing the channel by checking the distortion of signals along the lines using high speed scope.  Implementation of High Speed Serial channel on Stratix 2 GX board.

Serial Out  Transceiver – used for transmitting/receiving data in the PHY.  PHY – The physical layer of the OSI model consists of PCS, PMA and PMD - physical medium. PMA Analog Section PCS Digital Section n n FPGA m m  Applications – Gigabit Ethernet systems, wireless network routers, fiber optic and communication systems. Serial In

Amplitude dependent Noise:  CrossTalk: Capacitive & Inductive Coupling Shared Signal Return  ISI: Reflections, Oscillations, Inertial Delay.  Timing: Skew, Jitter.  Power Suppluy Noise.

Independent Noise:  Skin Effect  Ohmic Loss  Dielectric Loss
