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.
Then, the T
TERM-ON-PWM-RX
Time) is measured using a real-time oscilloscope. Among all measured
T
TERM-ON-PWM-RX
values are considered as the final results.
The test will pass if the maximum T
PREPARE time defined by the DUT´s LS_PREPARE_Length_Capability
attribute (see Table
This test is performed at each selected lane and PWM gear and it is tested
at the minimum and maximum data rate value for all gears.
