JT 5705/BO

Compact mixed-signal boundary-scan controller with I/O for simple integration in fixtures.

The JT 5705/BO has mounting holes for easy location within a fixture and presents all TAP signals and I/Os on 0.1″ pitch IDC connectors.

JT 5705 boundary-scan controllers offer a unique combination of two JTAG TAP controller (tester) interfaces plus 64 mixed-signal I/O channels (56 digital and 8 analog) in a compact design. Maximum TCK speed is 15 MHz and all voltages are fully programmable. Use the IO and analog features to measure power supplies, clock frequencies, test DACs and ADCs and improve coverage to test points and connectors.

An alternative fixture-oriented model is also available: JT 5705/IB as well as a desktop model: JT 5705/USB and a rack mount version: JT 5705/RMIc.
