Overview

ISO/IEC TR 14165-117:2007 - Information technology - Fibre Channel - Part 117: Methodologies for jitter and signal quality (MJSQ) is a Technical Report that defines measurement methods and signal-quality specification concepts for Fibre Channel physical interfaces. The report focuses on phase content (jitter) of high‑speed serial signals - both optical and electrical - and describes generalized methodologies for jitter compliance testing at signal levels including, but not limited to, the nominal receiver switching point.

Key topics and technical scope

The Technical Report covers practical and theoretical material used in signal‑performance verification, including:

• Jitter fundamentals and taxonomy
  • Definitions of jitter types (random, deterministic, bounded/unbounded) and their contributions.
  • Statistical behaviour and relationship between jitter distributions and bit‑error‑rate (BER).
• Measurement methodologies
  • Time‑domain and frequency‑domain techniques for jitter output and tolerance measurements.
  • Equivalent‑time oscilloscope (ETS) methods and enhanced ETS techniques for waveform and eye analysis.
  • Frequency‑spectrum methods and tail‑fit analysis for separating jitter components.
• Jitter timing reference and hardware considerations
  • Requirements for jitter timing references (e.g., Golden PLL performance for hardware implementations).
  • Considerations for measuring phase at different signal levels and during data acquisition.
• Signal quality specifications
  • Jitter eye‑mask methodology and 2‑D/eye‑mask approaches for processed and compensated signals.
  • Methods to determine compliance, including calculation of Level‑1 deterministic jitter (DJ) and total jitter (TJ) and verification approaches such as BERT or calibrated signal sources.
• Processed signals and compensation
  • How transmitter, interconnect and receiver equalization affect jitter and measurement methodology.
• Practical analysis
  • Data forms, separation of jitter components, frequency response, and effects of distribution changes on BER.
