WebDec 5, 2005 · 4 At this point the design is well on its way to being finished. The design could be simulated and it could also be functionally verified to be correct. 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.
