SATA Receiver Tests
Rx Jitter Tolerance Test (RSG-01 Gen1, RSG-02 Gen2, and RSG-03 Gen3)
The Rx Jitter Tolerance test is available for all data rates.
Purpose and Method
This Rx Jitter Tolerance Test verifies that the receiver is able to recover the
data in the presence of jitter and it is an official Rx test that has to be
passed in order to obtain SATA certification. This test is available for all
data rates such as:
• RSG-01 Gen1 Rx Jitter Tolerance Test runs at 1.5GBit/s (Supported
with M8020A BERT only)
• RSG-02 Gen2 Rx Jitter Tolerance Test runs at 3.0 GBit/s
• RSG-03 Gen3 Rx Jitter Tolerance Test runs at 6.0 GBit/s
A compliant DUT must pass all the tests, including that for the highest
data rate that it supports. Refer to the beginning of the Receiver Test
Procedures ( Receiver Tests ) for a description of the general operating
principle of all SATA receiver tests.
The stress signal applied to the data signal is RJ and SJ. There is a set of
compliance frequencies for the SJ. For each frequency, the DUT has to
loop back the pattern for the complete test duration without error. The test
duration for a single frequency at different data rates is given as:
• 10 minutes for RSG-01 Gen1 (1.5 GBit/s)
• 5 minutes for RSG-02 Gen2 (3.0 GBit/s)
• 2.5 minutes for RSG -03 Gen3 (6.0 GBit/s)
The compliance jitter frequencies are 5 MHz, 10MHz, 33 MHz, and 62
MHz.
