BERTScope PLA Phase Locked Loop Analyzers

SyntheSys Research’s BERTScope PLA Phase Locked Loop Analyzers are the first single instrument solution for validating the response of PLLs used for transmit clock generation in Add-In cards is compliant to PCIe test specifications. Conventional approaches use multiple instruments and require complicated setup, cabling and calibration. The BERTScope PLA simply requires the user to connect the four included cables to the PCI-SIG specified Compliance Base Board test fixture and connect the included USB cable to a PC. Once the control and display software is loaded from the included CD-ROM, the user is ready to test.

The BERTScope PLA instruments improve measurement confidence and repeatability by obtaining high accuracy with amplitude resolutions up to 100 times greater than spectrum analyzers. The test is fast – less than 15 seconds for a complete response scan – providing the throughput to allow characterizing a larger number of samples for improved statistical confidence. The new instruments provide additional data, including phase response, which is useful to the engineer characterizing their PLL design.

The BERTScope PLA is available in two models. The base model PLL-PCIE ($29,000 ) is dedicated to PLL response compliance verification. The CRJ 12500A-PCIE ($51,500) is based on the BERTScope CRJ, the highest performance instrumentation-grade adjustable clock recovery product available today. In addition to PLL response compliance verification, this product provides all of the clock recovery, jitter spectral analysis and Duty Cycle Distortion measurements available in the BERTScope CRJ 12500A.
