VSC7112 Two-lane PCI Express 3.0 Redriver with Adaptive EQ Microsemi's PCIe redriver delivers excellent performance with flexible lane configuration for Gen 1/2/3 applications in a very small footprint. Highlights VSC7112 is a high-performance, two-lane (quad-channel) asynchronous buffer that simplifies high-speed signal path designs (up to 8.5 Gbps) by providing Microsemi's industry-proven adaptive input equalization and output pre-emphasis. The device optimizes energy efficiency with innovative Green modes that reduce power consumption at lower data rates. Additional power savings can be achieved by deactivating unused channels and configuring the best output level settings for an application. * Energy-efficient Green modes The VSC7112 device offers programmable, static, and adaptive equalization settings to provide a comprehensive solution for countering signal degradation over a wide variety of transmission cabling and interconnect paths. The small package and two-lane configuration make the device an excellent fit for a wide variety of PCIe server applications challenged with long traces, cables and connectors, as well as NVMe solid-state drives (SSDs). * Up to 8.5 Gbps asynchronous operation * Adaptive equalization * Ability to configure lanes as 4-channel buffer, 2x2 matrix, dual 1:2 duocast, or dual 2:1 selector Applications * PCIe Gen 1/2/3 * NVMe SSDs * 1.5G, 3G, and 6G SAS/SATA Loss of signal (LOS) detectors with programmable thresholds are included on every input port. Each channel includes PCIe Gen 1/2/3 receiver detection and state machines. The VSC7112 can be configured for pass-through 4-channel buffer, dual 2 x 2 matrix, dual 1:2 duocast, or dual 2:1 selector configurations.
