PCI Express Chip Packs 8/16-Bit PIPE Host System Port

The GL9711 GigaCourier from Genesys Logic provides a 125-MHz 16-bit or 250-MHz 8-bit PIPE (PHY interface for PCI Express) interface to tie into the host system logic. This chip also offers a single-lane, 2.5-Gbit/s PCI Express serial port. With its parallel interface, system designers can add a PCI Express port to their systems without requiring a high-speed FPGA or ASIC.

The company plans to release a four-lane transceiver version of the chip, the GL9714, which it expects to sample next quarter. Both versions fully comply with the PCI Express base specification (revision 1.0a) and the PIPE architecture, version 1.0 from Intel Corp. Multiple four-lane transceivers can be used in systems that require 8, 16, or 32 lanes to meet the data-transfer needs of graphics, storage, and other applications.

In 25,000-unit quantities, the single-lane GL9711 sells for about $5 each. Samples are immediately available.
