 As technology have gotten faster, the demand for higher data transfer rates between devices has grown.  It turns out that the serial communication provides better solution, than the parallel one.  A known serial high speed communication protocol is PCI-Express.

 Implementation of high speed digital channel  Examining Stratix card ability of GX (protocols and parameters).  Testing the channel by checking the distortion of signals along the lines.  Learning and understanding the physical part of high speed channels.

Serilizer Encoding PLL Channel: rate: up to Gbps DeserilizerDecoding

Phase compensation Byte serializer * 8B/10B Encoder * Serializer PLL

Word Aligner Deserializer PLL+CRU Byte Deserializer * 8B/10B Decoder * Rate matcher * Phase compensation

 The channel will be implemented using Stratix 2 GX card. Working tools: 1) Quartus 2 – Design and programming in VHDL. 2) Hyperlinx – Simulation of transmissions lines.

 Serial channel rate: 600[Mbps]-6.375[Gbps]  PLL ref. clock rates [MHz]  Varies types of functional modes : PCIE, SONET/SDH, GIGE, Basic, XAUI.  Receiver termination (100,120,150)  Pre-emphasis and equalization  8B/10B coding  Rate matcher  Byte deserializer
