Application:
Single Port DS3/E3 ATM Advanced
Mezzanine Card for Telecom Edge Access
PLX Product:
PEX 8111 - x1 PCIe to PCI Bridge
Key Benefit:
Leverage PCI-based Designs into PCI
Express
Telecom Systems Move to PCI Express
High availability telecom edge access
applications systems have adopted PCI
Express (PCIe) to allow systems to
deliver high performance, better
reliability, smaller size, lower cost and
performance scalability into the future.
T h e P C I I n d u s t r i a l C o m p u t e r
Manufacturing Group (PICMG) has
developed the ATCA (Advanced Telecom Computing Architecture)
standard, migrating the PCI-based CompactPCI specifications,
using PCIe-based I/O standards. One such
specification is the AMC.1 (a.k.a. Advanced
Mezzanine Card), which is a hot swappable
daughter card for ATCA system boards. The
AMC.1 specification calls out PCIe as the
interconnect standard. Many of the existing cPCI
functions are now required in the AMC form
factor. This requires the cards to have new I/O
interfaces. Redesigning the I/Os on the OC-3 SAR chip to support
PCIe is a costly and time-consuming activity, and actually may never
happen due to IP required to deploy PCIe.
This Transition Calls for a Bridge
The PEX 8111 from PLX provides the tra
