The real world problem
PCI Express (PCIe) is a computer standard designed to replace the older PCI, PCI-X and AGP bus standards. PCIe has a number of improvements over previous bus standards including:
PCI Express is used in consumer, server, and industrial applications, as a motherboard-level interconnect (to link motherboard-mounted peripherals), a passive backplane interconnect and as an expansion card interface for add-in boards.
In virtually all modern PCs, from consumer laptops and desktops to enterprise data servers, the PCIe bus serves as the primary motherboard-level interconnect, connecting the host system processor with both integrated-peripherals (surface mounted ICs) and add-on peripherals (expansion cards.).
In the consumer space, time to market is everything. Our customer, designing on TSMC's 90nm process, needed a PCIe SerDes to complete the functionality of their device. To maximize access to their emerging market they needed a rapid, right first time design.
Utilising previous silicon proven experience with much more technically challenging state-of-the-art SerDes applications like SONET, AnSem was able to complete this development in a short time allowing our customer to quickly gain access to the market without missing their window-of-opportunity.
Our modular IP contains two separate macros which allow the customer to make silicon efficient multi-lane PCIe interfaces if required. Furthermore, the IP contains a number of assets to increase the overall flexibility:
