What is Adaptive Clocking Technology™

Adaptive Clocking eliminates instabilities typically associated with boundary scan (JTAG) operation at high clock rates (TCK) due to path delays. This proprietary and patented design compensates for path delays allowing the JPCI controller to operate at the maximum TCK rate supported by the target devices.
  • Clocking flexibility to achieve highest throughput
  • Automatic compensation for path delays from 10 nsec to 10 µsec – with 10 nsec resolution
  • Reliable high-speed operation over long cable lengths without the use of Pods (system to DUT)
  • Cable length of up to 15 meters (40 – 50 feet)
Adaptive clocking eliminates the effects of path delay allowing the JPCI controller to be located at an ergonomically suitable distance, up to 15 meters from the target.
Boundary Scan - Adaptive Clocking Technology
Our Competitors will suggest to you to:
  • Keep the cables connecting the target to the controller as short as possible!!
  • Reduce the TCK rate down until the operation becomes stable!
  • Use re-timing POD or cable!
These are not technically elegant solutions, they are crude work-arounds that may not work. They create:
  • Impractical set-ups and pose extreme limitation on application of Boundary Scan in a real production environment
  • Reliability problems can cause false/misdiagnosis
  • Reduction of TCK rate will impact throughput, in device programming applications this will cause severe delays and wasted time
  • Impedes the integration of Boundary Scan with other systems and processes
