Keysight N5990A MIPI M-PHY Receiver Test User Guide
The data generator sends Burst-mode CJTPAT signaling with nominal
amplitude settings while the DUT is configured for Terminated-mode or
Non-Terminated-mode depending on the test case.
The TOL is the ratio of the PWM Receive Bit Duration (T
PWM-RX
and the average of N PWM receive bit durations in PWM-MODE. The
TOL is tested for the conformance limit values (0.82/1.18) and for
PWM-RX
the given Additional Steps. At each step, the BER is measured and
compared with the Target BER to consider the pass/fail result.
This test is performed at each selected lane and PWM 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 (in Expert Mode), for this tolerance test are as follows:
• 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
• IBerReader Init Mode
• Test Sequence
• Re-Init sequence after Reset DUT
• Lane Under Test Termination Mode
• Min Tested
• Max Tested
• Additional Steps
