Advanced equalization consisting of CTLE and DFE is needed for current and future generations of serial data standards to compensate for loss and maintain required bit error rate. The jitter decomposition methodology that emerged few decades ago was the first attempt to better understand the source of timing variations and effect on link performance. While such analysis after CTLE is straightforward, measuring jitter after DFE still is not fully understood or standardized. The paper will discuss models and practical measurement considerations for jitter measurements after DFE as well as implications for transmitter compliance testing in various standards.
Understand how jitter transforms and affects the receiver with decision feedback equalizer. Learn about different DFE implementations and behavioral models used in compliance testing.
Basic understanding of serial data link, transmitter and receiver equalization, CTLE and DFE operation is desirable.
