11. Testing and Analysis for Jitter and Signaling Integrity for High-Speed Links

This chapter focuses on testing aspects of jitter and signaling for an I/O link system. Link signaling and its governing roles in determining test requirements and methodologies are discussed first. Then specific test requirements and methods are introduced for link subsystems of transmitter (Tx) output, channel output, receiver (Rx) input and tolerance, PLL output, and reference clock output within the context of leading link architectures. The importance of the roles for clock recovery (CR) and associated jitter transfer function (JTF), equalization (EQ), jitter components, and statistical samples in testing jitter and signaling are emphasized. System-level tests ...
