TX emphasis is measured at the mated Serial ATA connector at the device. Unless otherwise specified, no CIC is used for this measurement. b The TX emphasis requirement does not apply to the Internal 4 -lane cable mated to a backplane or devices using the Internal LIFSATA connector, the SATA MicroSSD interface, or the Internal M.2 connector.

9/5/2014 · The SATA spec does not specify Tx emphasis. The realities of today’s marketplace dictate that this shortcoming be rectified due to the recent introduction of extremely challenging host architectures equipped with chipsets providing extensive programmability of both Tx emphasis, The proposed approach of this TPR is to specify that TX emphasis be calculated from the voltage ratio of the first bit and second bit of MFTP. Both bits are sampled between 0.45 and 0.55 of their respective UIs. This proposal is being presented by Western Digital. Make the following Changes to SATA 3.2 as modified by TPR_059.

amount of emphasis is the difference between pre- emphasis and de- emphasis . The advantage of this implementation is that it dissipates less power than the traditional pre- emphasis and achieves the same amount of emphasis . Limitations of Pre- Emphasis Pre- emphasis increases the signal edge rate, which increases the crosstalk on the neighboring channels.
