Boundary-scan tool supports USB, Ethernet, and FireWire
Staff -- Test & Measurement World, 6/1/2004
JTAG Technologies' DataBlaster JT 37x7/TSI (short for Triple-Serial Interface) offers IEEE 1149.1 boundary-scan testing with a choice of USB 2.0 (and 1.1), Ethernet, or FireWire interfaces. Suitable for in-system programming (ISP) of flash memories and CPLDs and for complex digital circuit testing, the new product offers sustained test-clock speeds to 40 MHz by use of the vendor's proprietary ETT (Enhanced Throughput Technology) system, and it features a flash image buffer memory that may be expanded to 128 Mbits.
Supplied with the vendor's complementary QuadPOD, the new DataBlaster/TSI offers four synchronized TAPs (test access ports) able to support multi-TAP test targets (UUTs) or gang programming of four single TAP targets. QuadPOD is "low-voltage ready," programmable per TAP. The scalable DataBlaster JT 37x7/TSI range starts with the low-cost entry model JT 3707/TSI. This unit has the same high-speed 40-MHz test capability as the extended models JT 3717/TSI and JT 3727/TSI but is not fitted with an ETT module for flash ISP.
To provide maximum reverse compatibility, new DataBlaster/TSI units are fully compatible with the vendor's existing test and ISP files. Compliant programs include test-development software, flash and PLD development software, and production tools for stand-alone and integrated test platforms. There is also support provided to execute tests under National Instruments' TestStand, LabView, and LabWindows/CVI environments.
Base price: $4000. JTAG Technologies, Stevensville, MD. 877-367-5824; www.jtag.com .
