equalization
VSC7109 is a high-performance, quad-channel asynchronous buffer
that simplifi es high-speed signal path designs (up to 3.5 Gbps) by
providing Microsemi’s industry-proven signal equalization at both the
inputs and the outputs. The device optimizes energy effi ciency with
innovative Green modes that lower power consumption. Additional
power savings can be achieved by deactivating unused channels and
confi guring the best output level settings for an application.
The VSC7109 device offers programmable, static, and adaptive
equalization settings to provide a comprehensive solution for countering
signal degradation over a wide variety of cabling and interconnect
transmission paths in server, video, and storage applications.
VSC7109 is fully compatible with the latest server, video, interconnect,
and storage protocol data rates including Ethernet, HDMI 1.4, 3G SDI,
PCIe Gen 1, and SAS/SATA.
Loss of signal (LOS) detectors with programmable thresholds are
included on every input port. Out-of-band (OOB) signal forwarding can
be enabled on each output. The VSC7109 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.
