VSC7112 Two-lane PCI Express 3.0 Redriver with Adaptive EQ Microsemi s PCIe redriver delivers excellent performance with exible lane Highlights con guration for Gen 1/2/3 applications in a very small footprint. Up to 8.5 Gbps asynchronous operation VSC7112 is a high-performance, two-lane (quad-channel) asynchronous Energy-ef cient Green modes buffer that simpli es high-speed signal path designs (up to 8.5 Gbps) by Adaptive equalization providing Microsemis industry-proven adaptive input equalization and output Ability to con gure lanes as 4-channel buffer, pre-emphasis. The device optimizes energy ef ciency with innovative Green 2x2 matrix, dual 1:2 duocast, or dual 2:1 modes that reduce power consumption at lower data rates. Additional power selector savings can be achieved by deactivating unused channels and con guring the best output level settings for an application. Applications The VSC7112 device offers programmable, static, and adaptive equalization PCIe Gen 1/2/3 settings to provide a comprehensive solution for countering signal degradation NVMe SSDs over a wide variety of transmission cabling and interconnect paths. The small package and two-lane con guration make the device an excellent t for a 1.5G, 3G, and 6G SAS/SATA wide variety of PCIe server applications challenged with long traces, cables and connectors, as well as NVMe solid-state drives (SSDs). 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 con gured for pass-through 4-channel buffer, dual 2 2 matrix, dual 1:2 duocast, or dual 2:1 selector con gurations.
