A 6Gbps serial link transmitter with pre-emphasis

Abstract

In this paper, we propose a novel 6Gbps SATA transmitter. The transmitter is constructed by PISO, driver, pre-emphasis and PLL for a 1 similar to 5 meter cable. A test chip of transmitter with PLL and on-chip termination is implemented to verify the design methodology. The overall circuit is implemented in TSMC 0.18um 1P6M 1.8V CMOS process. The whole measured transmitter jitter is about 44ps and the power consumption is 68mW for 6Gbps case.
