Keysight N5990A MIPI M-PHY Receiver Test User Guide
The data generator sends Burst-mode CJTPAT signaling while the DUT is
configured for Terminated-mode. In Compliance Mode, the differential
voltage amplitude and the common-mode are set to the nominal values
(200mV). In Expert Mode, two Level Pairs are tested, the differential
voltage amplitude is set to the minimum (60mV) and maximum (245mV)
conformance values while the common-mode is kept to the nominal value
(150mV). No other signal impairments such as the ISI channel or the jitter
sources are added to the signal.
In Compliance Mode, the Frequency Offset is tested for the maximum and
minimum conformance level: +2000/-2000 ppm. At each step the BER is
measured and compared with the Target BER to consider the pass/fail
result.
In Expert Mode, each Tested Frequency Offset value is tested over the
given Tested Range. In this case, the result will show the minimum and
maximum frequency offset values at which the DUT works properly and the
test will pass if those values are within the spec limits.
This test is performed for all selected HS lanes and gears. It is only
required for the Terminated case. In Unipro Test Mode and with the option
"Lane Test Mode" set to Simultaneously, the different lanes are tested in
parallel for each gear.
Refer to the connection diagrams shown in the Connection Diagram
section of the Test 2.1.1- HS-RX Differential Input Voltage Amplitude Test
test.
The parameters used in Expert Mode for this test, are as follows:
• Lane Under Test Termination Model
• CDR Loop Bandwidth (if CDR is selected in the Special Parameter
dialog, see "BERT Analyzer
• CDR Peaking (if CDR is selected in the Special Parameter dialog, see
"BERT Analyzer Settings")
• CDR Transition Density (if CDR is selected in the Special Parameter
dialog, see "BERT Analyzer
• CDR Loop Order (if CDR is selected in the Special Parameter dialog,
see "BERT Analyzer
• Target BER
Settings")
