External PCI Express (PCIe) x1, x4, x8, x16 I/O Products

1 External PCI Express (PCIe). x1, x4, x8, x16. I/O Products INTRODUCTION External PCI Express (PCIe). Molex interconnects extend PCI Express outside the box External PCI Express is a new, multi-purpose, hot- n Split systems or disaggregate PCs, desktop consoles pluggable input/output (I/O) interface that can be that contain removable media drives, memory used across the computing industry, from mobile modules, I/O ports and audio jacks equipment through high-end servers as well as n I/O expansion to extend the I/O card capabilities communication equipment.

2 These connectors were of the main system for support of different form designed to fit all popular mechanical architectures factors, including legacy systems for test and without special or custom versions. measurement and for instrumentation Molex technology provides future scalability and n Server expansion I/O to support conventional PCI. flexibility by supporting Generation 1 PCIe data rates Express add-in cards and Express modules at through Generation 2 data rates of n Graphic subsystems (controller and memory). Gbps. located External to the main system x1 18-Circuit TDP.

3 The broad usage and versatility of this technology PCIe connectors and cables from Molex are available allows for cabled-system extensions to External I/O in multiple configurations including a high durability subsystems, meeting the needs for specific applications x1 configuration (rated for 1500 mating cycles) and which include: x4, x8 and x16 configurations (rated for 250 mating cycles). In addition, test boards are available to meet customer evaluation and development requirements. PCIe Protocol Generation 1 Generation 2. Bandwidth (Gbps) x4 38-Circuit iPass.
