Keysight N5990A MIPI M-PHY Receiver Test User Guide
When using loopback, the hibernate state exit is found by detecting that
the DUT has activated the loopback mode and sent the test pattern back
via the TX. The test pattern must contain a configuration block starting
with the macros SQUELCH().
When using UniPro Test Mode, it is observed that the DUT gets into Test
Mode and starts sending FILLER symbols back.
The DUT should not exit the hibernate as long as the pulse width is less
than the squelch detection limit (T
considered conformant.
Refer to the connection diagrams shown in the Connection Diagram
section of the Test 2.4.3-SQ-RX Squelch Exit Voltage (VSQ) test.
