EqcoLogic Technology

In recent years there has been an explosion in the use of high speed serial links to replace parallel buses and analog connections. This has transformed the way computers communicate both internally, via technologies such as SATA, replacing PATA and PCI Express, replacing PCI, and externally, via USB, firewire, HDMI etc.

Equalization

As serial data communication speeds increase the electrical loss of the cable (due to cable capacitance, inductance and skin effect) also increases making it difficult to send high speed digital signals over long distances at low power.

In other words, the "eye diagram" (left panel, top), a measure of the ability of the receiver to distinguish between '0's and '1's, becomes closed.

Eqcologic's analog cable equalizer technology measures this loss and automatically restores the high frequency components of signals degraded by transmission over a long cable (left panel, bottom) and thus is able to "open your eyes™.

EqcoLogic Technology

With the growth of high speed serial data transmission has come increasing complexity of cables and connectors. These are now frequently a major element of cost in digital applications. EqcoLogic has developed novel silicon devices that allow very high speed data transport over conventional, low cost cables and connectors, especially traditional coaxial cables.

Equalization technology overcomes degradation of digital signals due to attenuation over an electrical conductor. The compensation applies to conductor length limitations, data rate restrictions or both.

EqcoLogic Transceivers

EqcoLogic’s transceiver family transmits data in a duplex manner (both ways over the cable at the same time). They also support transmission of power over the cable.
