Fix slow rgmii rise time
WebMay 21, 2015 · If the rise time improves (smaller) while drastically reducing the input (and output) level the cause is the limited slew rate (large signal effect). Otherwise, it is the limited small-signal bandwidth. In this case, the rise time should improve while reducing the gain value (more feedback, wider bandwidth).
