JT 2122/MPV
Digital I/O Scan (DIOS) module with up to 128 or 133 ‘boundary-scannable’ I/Os in a standard DIMM-168 format.
To increase the test coverage of a printed circuit board the JT 2122/MPV fits directly in 168-pin DIMM sockets mounted on a PCBA to test the connectivity of those sockets.
The TAP signals can be accessed via the ‘fingers’ of the 168 pin module connector or a separate 10-pin connector. A TAP-out can be used to daisy-chain to another DIOS module or to a scan chain on the target board. The JT 2122/MPV is often used in conjunction with a JT 2702/DDC Dual DIMM Carrier ‘break-out’ board to create a high-density DIOS module. Two JT 2122/MPVs can be housed in one JT2702/DDC will provide 256 channels in a small footprint, ideal for mounting in test fixtures.
