Express Boundary-Scan from JTAG Technologies
Stevensville, MD — JTAG Technologies has added to its line of high-performance boundary-scan IEEE Std. 1149.1 controllers. Known as the DataBlaster JT 37x7/PCIe, the new unit offers support for the now popular PCI-express slot format found extensively in today's PCs. The PCIe bus is a high-speed serial replacement of the older parallel PCI bus.

In keeping with industry demands, the new boundary-scan controller satisfies the burgeoning requirements for high speed In-System Programming (ISP) of flash memories and CPLDs and complex digital circuit testing. The new DataBlaster JT 37x7/PCIe offers the user sustained test clock speeds of up to 40MHz by use of the company's proprietary ETT (Enhanced Throughput Technology) system and includes a flash image buffer memory which may be expanded to 128 Mbits.

Supplied with the complementary QuadPOD also from JTAG Technologies, the new DataBlaster/PCIe 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" and the advanced technology also allows maximum test speeds at the target by incorporating high-speed signal conditioning, logic threshold adjustments and cable delay compensations in a compact, remote, extension module.

The scalable DataBlaster JT 37x7/PCIe range starts with the low-cost entry model JT 3707/PCIe, suitable for high-speed 40MHz test applications and in-system PLD programming. Companion models JT 3717/PCIe and JT 3727/PCIe, optionally fitted with an ETT module for flash ISP, support high-throughput flash programming as well as test and PLD programming. The flexible nature of ETT allows it to support memories with various data-bus widths from 1-bit to 64Kbit. DataBlaster PCIe units are fully compatible with all revisions of the company's test and ISP tools, such as JTAG ProVision and the former "Classic" family of development and run-time packages.
