A 6Gbps Serial Link Transmitter with Pre-emphasis

In this paper, we propose a novel 6Gbps SATA transmitter. The transmitter is constructed by PISO, driver, pre-emphasis and PLL for a 1-5 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 0.18 mum 1P6M 1.8 V CMOS process. The whole measured transmitter jitter is about 44ps and the power consumption is 68 mW for 6Gbps case.
