• NVMe SSDs
• 1.5G, 3G, and 6G SAS/SATA
Microsemi's PCIe redriver delivers excellent performance with fl exible lane
confi guration for Gen 1/2/3 applications in a very small footprint.
VSC7112 is a high-performance, two-lane (quad-channel) asynchronous
buffer that simplifi es 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 effi ciency with innovative Green
modes that reduce power consumption at lower data rates. Additional power
savings can be achieved by deactivating unused channels and confi guring
the best output level settings for an application.
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 confi guration make the device an excellent fi t for a
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 confi gured for pass-through 4-channel
buffer, dual 2 × 2 matrix, dual 1:2 duocast, or dual 2:1 selector confi gurations.
