Web1 okt. 2024 · A 12 Gbit/s feed-forward equalisation (FFE) transmitter has been designed in 65 nm CMOS process. The three-tap/half-rate high-speed tap signal generation technique for the segmented FFE driver is presented. A clock buffer scheme to make the equivalent signal transition for each segmented unit contributes to a low jitter performance. ffe = serdes.FFE(Name,Value) sets properties using one or more name-value pairs. Enclose each property name in quotes. Unspecified properties have default values. Example: ffe = serdes.FFE('Mode',1) returns an FFE object that applies specified tap weights to the input waveform. my little big truckWeb4 aug. 2024 · Each lane with a configurable serialization scheme was adapted to adjust the data rate flexibly.
