Ethernet clock tolerance

WebJan 18, 2024 · CAN clock tolerance should be ± 1.58% for baud rates up to 125 kbps and 0.5% for higher rates. For PSoC 4, CAN clock source is HFCLK and for PSoC 3 and PSoC 5LP, the clock source is BUS_CLK. Make sure that these clocks are derived from high accuracy clocks. Here are the options to use an accurate CAN clock for PSoC 4 CAN … WebAnother similarity is that there is a strong desire to retain a clock tolerance spec of +/-100 PPM. One of the key differences between GbE and 10 GbE is that data is moving 10 times as fast for 10 GbE. Clock tolerance compenstation for Gigabit Ethernet products is performed above the Physical layer, usually within a switch and between links.
