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 transitional silicon solution. It allows the AMC designer to leverage an existing cPCI design, which uses PCI-native silicon, directly into the AMC.1 form factor. The 32-bit PCI-native SAR connects directly to the PEX 8111 PCI bus and is converted into the PCIe protocol with very little impact to power or board space. Issue No. 27 AMC Card Gets Into the ExpressLane Here’s a closer look at the design of the AMC Card. It is a single wide, full height, AMC.1 compliant ATM adapter, featuring a front I/O full duplex DS3/E3 interface. This card uses PCIe to communicate with the host processor in an ATCA system. The Segmentation and Reassembly (SAR) segments and reassembles AAL0, AAL3/4, and AAL5 cells. It will manage and pass AAL1, AAL2, and raw cells. This card includes one full duplex DS3/E3 port. Key Advantages of Using PLX PLX is the industry’s leading supplier of PCI Express I/O interconnect Switches and Bridges . The company is focused on the design and support of silicon in the first wave of PCI Express systems. PLX is also an Executive Member of the PICMG and was a key contributor to the newly released PCI Express AMC.1 specification. The PEX 8111 Bridge has become the de-facto standard for upgrading PCI components and adapter cards to the AMC form factor. Lead-Free Packaging Available NOW! The PEX 8111 is available in lead-free, RoHS- compliant versions as well as the traditional leaded packages.
