Discussion:

Reference [1] specifies the Transmitted Signal conformance limits for SATA products. Reference [2]

provides the definition of this term for the purposes of SATA testing. Reference [3] defines the

measurement requirements for this test.

The minimum TX differential amplitude is a measurement of the minimum eye opening terminated into a

laboratory load after the CIC, projected to a 1E-12 BER contour at the 50% location of the bit interval. The

Lone-Bit Pattern (LBP) is used for this measurement, and the 50% eye location is determined by the

compliant, JTF-defined PLL clock recovery defined in [3].

This test requirement is only applicable to products running at 6Gb/s.

Minimum Voltage Measurement of LBP at JTF-Defined clock location (50%) at BER level of 1E-12
