The wide spread and rapid development of cell phones from simple voice-capable devices to smartphones or even tablet PCs with the constant addition of capabilities and features came along with a proliferation of interfaces between ASICs and “sensors” and “terminal devices” such as microphones, cameras, loudspeakers, displays, and peripheral electrical devices which make ASIC development and system integration an increasingly difficult task.
This application note focuses on the requirements for testing ASICs according to the MIPI specification and CTS using the new AXIe J-BERT M8020A, this highly integrated test setup simplifies the required complex jitter cocktail and test automation enables in-situ calibration making testing an easy task.
The modularity of the AXIe J-BERT provides the flexibility to adapt to test needs and budget. For example, different speed options can be selected, depending on the requirements. The test system can also be configured as single or dual channel modules and additional modules can be added, to address the increased number of lanes that need to be tested. The modules can also be configured as a generator only (omitting the ED), when the DUT does not need to be tested in loopback mode or if it does not support it.
