Flag based all digital timing recovery

WebA traditional symbol timing recovery architecture that used in 100BASE-T and 1000BASE-T is multi-phase selection based phase-locked loop (MPS-PLL). In 10GBASE-T system, the echo (ECHO) interference suppression requirement is much higher and hence the ECHO canceller is more sensitive to the timing jitter as well than that of 1000BASE-T system. WebSep 9, 2024 · $\begingroup$ Would you consider using an actual timing loop? I think you will find it actually simpler in implementation and more robust that a “brute-force” approach. The preamble sequence is good to establish initial acquisition for the packet especially in lower SNR conditions and then the timing loop will use current symbols along with past …
