Abstract :
An SST transmitter is described with ground regulation, P-to-N shunting and partially weighted segments for fine granularity level/equalization. Clocks and datapath dissipate 32mW at 7.4Gb/s with an 800mV eye for a power efficiency of 4.32mW/(Gb/s). Measured total jitter is 209.6mUI or 28.3ps at 10-12 BER. Target protocols include PCIe G1/2, XAUI, FC 1/2/4, CEI6 MR and SATA 1/2.
