FILAR
Quad HOLA S-LINK to 64-bit/66 MHz PCI Interface


DESCRIPTION

The FILAR (Four Input Links for Atlas Readout) is a highly integrated PCI interface that can move data from up to four HOLA S‑LINK channels to a 32-bit or 64-bit PCI bus that runs at 33 MHz or at 66 MHz. Four HOLA Link Destination channels are integrated on the FILAR. The channels are fully compatible to HOLA Link Source Cards and each can receive data at a speed of up to 160 MB/s. The PCI interface part is based on the design of the S32PCI64 interface.

It is foreseen that the FILAR interface card will be used for testing, commissioning and installation of the ATLAS Readout Drivers.

Features

The main features of the interface are:
