Intellitech ships multi-voltage JTAG multiplexer

Durham, N.H.—Intellitech Corp. has shipped a multi-voltage eight ring JTAG multiplexer called the Scan Ring Linker (SRL) in a 16mm x 16mm VQ100 package to early adopters.

The SRL lowers PCB costs and reduces engineering design time by eliminating pull-up/pull-down resistors, buffer ICs and voltage translators needed for designing and routing JTAG rings in complex PCBs and systems, especially those with mezzanine cards.

The SRL enables partitioning of the PCB 1149.1/JTAG infrastructure on-the-fly into short faster rings or to access plug-in daughter boards with JTAG components.

The SRL provides four buffered TCK and TMS pairs per local JTAG port. The JTAG controlled TCK and TMS copies reduce performance limiting loading capacitance while preserving testability for scan-chain shorts and opens. The SRL includes wide-capture, which enables higher JTAG test frequencies for PCBs with long JTAG routing and transparent test-logic-reset, which enables test-logic-reset commands to propagate to compliant ICs without losing the SRL ring configuration.

The IC compatibility modes enable third party tools such as emulators and FPGA programming pods to access the scan rings.

Pricing: Starts at $5.15 in 1K quantities.
Availability: In a leaded or RoHS and commercial or industrial temperature ranges.
