The History of PCIe: Getting to Version 6

Mar. 15, 2021 PCIe, or Peripheral Component Interconnect Express which nobody ever says, was an upgrade to the earlier PCI bus. This was developed by Intel and introduced in 1992. It replaced several older, slower buses that had been used in a somewhat ad-hoc fashion in early PCs. It was primarily a 32-bit bus, although the standard allowed for 64-bit. Most importantly, it was a parallel bus. Today, it is only of historical interest and is no longer in active use, so I won t go into any detail. In 2004, a group of Intel engineers formed the Arapaho working group and started to develop a new standard. Eventually, other companies joined the group. The design went through several names before settling on PCI Express (PCIe). In some ways, it is a successor of PCI, in that it serves a similar function. In other ways, it is a completely different type of design. In particular, it is a serial bus, more like a network-on-a-board than the old-style parallel interface of PCI (and pretty mu

PCIe 4 0 PHY IP with 16GT/s optimized for low power consumption (Silicon Proven in TSMC 12FFC)

This Peripheral Component Interconnect Express (PCIe) x4 PHY is compliant with PCIe 4.0 Base Specification with support of PIPE 4.4 interface spec. Lower power consumption is achieved due to support of additional PLL control, reference clock control, and embedded power gating control. Also, since a fore mentioned low power mode setting is configurable, the PHY is widely applicable for various scenarios under different consideration of power consumption. T2M provides a portfolio of silicon-proven IP for PCI Express consisting of controllers, PHYs, verification IP, IP Prototyping Kits, Software Development Kits and Interface IP Subsystems. As the industry standard for PCI Express, solution which T2M offers is in volume production and has been successfully implemented in a wide range of applications.
