XJLink2-CFM - Boundary Scan for Teradyne TestStation

XJLink2-CFM - Boundary Scan for Teradyne TestStation Description:

Improve test coverage and reduce cost.

The XJTAG XJLink2-CFM adds the power of XJTAG’s boundary scan solution to the Teradyne TestStation, giving test access to hard-to-probe parts of a board. Both JTAG and non JTAG devices, such as Flash, RAM, Ethernet controllers, SPI, and I²C devices can be tested without physical probe access, reducing probe count and fixture cost, while increasing the test coverage. In addition to testing, memory devices, FPGAs and CPLDs can be programmed.

• Fully compatible with all XJTAG software
• High-speed programming – via JTAG, SPI, I²C, or custom protocols
• Up to 4 JTAG chain connections to UUT
• TCK clock frequencies up to 166 MHz
• Two different interface voltages can be configured, from 1.1 V to 3.3 V
• Adjustable signal slew rate, drive strength
• Automatic signal skew control
• Frequency counter on all I/O pins – Frequency input up to 200 MHz
• Fits into one slot on the Teradyne Multi-Function Application Board
• Optionally fit one or more XJLink2-CFM controllers or XJLink2-CFMx cards per Teradyne board

With a JTAG solution installed internally to the TestStation In-Circuit Test System, the complexity and recurring cost impact of fixture-based test can be significantly reduced, while improving overall test coverage.

This new integrated product enables streamlining of the production line, while also boosting fault coverage, thanks to the combination of XJTAG’s advanced connection test and non-JTAG device testing/programming with Teradyne’s In-Circuit Test capabilities.

The XJLink2-CFM is an advanced multi-TAP JTAG controller that fits into one of four Custom Function Module (CFM) locations on the Teradyne Multi-Function Application Board. A single or multiple XJLink2-CFMs can be added to the same Teradyne card for supplementary test and program capabilities, for instance testing panels of boards. XJLink2-CFMx expander cards are also available to maximize available connectivity from an XJLink2-CFM controller, from a maximum of 8 fixture-connectable signals when just using the XJLink2-CFM, up to 18 signals by adding one, two or three XJLink2-CFMx cards.

The test interface of the XJLink2-CFM is completely configurable allowing support for almost any programming protocol, not just JTAG devices. Programming speeds close to the theoretical maximum of a device can be achieved using the advanced features of the XJLink2-CFM.

The XJLink2-CFM is compatible with the standard USB XJLink2, so boards can be debugged at a repair station without having to develop a separate test setup. “Adding JTAG boundary scan functionality to the Teradyne test platform provides manufacturers with a robust, comprehensive test and programming environment,” says Simon Payne, CEO XJTAG.

Flexible licensing options also aid ease of use – the product can contain an XJTAG software license and allow standalone operation without additional dongles or network access. The system can also be licensed from a network server allowing the maximum use of XJTAG products without having to move licensed hardware between machines.

XJTAG offers a free trial and board setup to new users who are interested in taking an evaluation.
