Ny boundary-scan controller

JTAG Technologies lancerer boundary-scan controller til PCI-express slots (in english).

JTAG Technologies, a leading provider of IEEE Std. 1149.1 solutions for testing and programming high-density PCBs, announces a further extension of 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.

Following industry demands JTAG Technologies have developed the new, boundary-scan, controller to satisfy 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 JTAG Technologies proprietary ETTT (Enhanced Throughput Technology) system and features a flash image buffer memory which may be expanded to 128 Mbits.

Supplied with the complementary QuadPODT, also from JTAG Technologies, the new DataBlaster/PCIe offers four synchronised TAPs (Test Access Ports) able to support multi-TAP test targets (UUT's) or gang programming of four single TAP targets. QuadPODT 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, ideal for high-speed 40MHz test applications and in-system PLD programming.  Companion models JT 3717/PCIe and JT 3727/PCIe, optionally fitted with an ETTT module for flash ISP, support high-throughput flash programming as well as test and PLD programming. The flexible nature of  of ETTT 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 JTAG Technologies test and ISP tools, such as JTAG ProVision and the former 'Classic' family of development and run-time packages.
