XJLink-PF40 JTAG controller

28 February 2025 Test & Measurement

XJTAG, a specialist in electronic testing, has released its new XJLink-PF40 JTAG controller together with version 4 of its popular PCB software testing suite. The PF40 targets complex, high-density printed circuits and is aimed at design and test engineers taking a product from prototype through to manufacturing.

The XJTAG-PF40 has up to eight JTAG test access ports (TAPs) across 40 I/O pins responsible for interpreting the TCK and TMS signals. This allows one unit under test (UUT) to have multiple access points. One excellent feature of the PF40 is that each TAP has a configurable frequency. By allowing different frequencies for each TAP and having four voltage domains means that each connector can run in its own domain during testing.

A new connector pin-out for the 4 x 20-way connectors allow for easy configuration; odd-numbered pins are configurable as I/O and even-numbered pins are connected to ground. This improves signal integrity and ease of connection. The controller is protected against voltages of ±30 V on any pin.

For added protection the PF40 is encased in an aluminium housing and is used across a wide range of industries including research & development, testing, and manufacturing across all sectors in industry.
