Corelis PCI-1149.1/Turbo JTAG Scan Controller Module

The Corelis PCI-1149.1/Turbo is a high-performance JTAG scan controller module designed for PCI bus integration. It streamlines boundary-scan testing, debugging, and in-system programming of complex electronic assemblies through IEEE 1149.1-compliant JTAG operations. The module delivers high-speed scan clock frequencies dependent on PCI bus limits and target device characteristics, with integrated buffering that minimizes latency between the host system and JTAG interface. TTL/CMOS signal levels support standard JTAG connections (TDI, TDO, TCK, TMS, TRST) and multiple independent scan chains for simultaneous testing across board sections or different devices.
