N4880A Ref Clk Multiplier for PCI Express, MIPI M-PHY and SD UHS-II

Accurate and simplified receiver testing for PCI Express, MIPI M-PHY and SD UHS-IIThe N4880A reference clock multiplier fills a critical requirement for R&D and test engineers who need to characterize and re the next generation of PCI Express main boards, MIPI M-PHY chipsets and SD card UHS-II host devices. With its support for multiple reference-clock rates, the N4880A will help you accurately characterize and verify standards compliance under easy-to-reproduce test conditions.Lock the stressed-pattern generator to a system reference clockIn common reference-clock architectures, where the host cannot be driven by an external reference clock it’s necessary to lock the stressed-pattern generator to the same system reference clock used by the receiver under test. This is because the receiver under test also derives its sampling clock from this reference clock. Locking the stressed pattern generator to the same reference clock as the receiver under test ensures accurate and reproducible jitter-tolerance test results.
