Extended Common Mode LVDS
When considering noise margin, differential signals have the advantage that unwanted noise will generally be coupled onto both lines of the differential pair thus maintaining the relative polarity between the positive and negative channels.
But what happens when the amplitude of the noise forces both signals beyond the receiver common mode?
The LVDS TIA/EIA-644A standard requires +/-1 V of common mode noise margin, sufficient for many applications. Distributed systems or noisy environments can often see ground shifts that exceed 1V and for this reason Telefunken offers extended common mode LVDS devices to maximum noise margin.

Signals travelling through cables and backplanes suffer distortion due to attenuation, with the amount of loss increasing at higher data-rates. The result is jitter, which causes bit-errors and reduces the cable or backplane effective reach.
Techniques such as Equalization and Pre-emphasis attempt to compensate for loss by boosting the signal strength to correspond to the loss signature. Appropriate Signal Conditioning requires both knowledge of the media loss characteristics, and the design know-how and process capability to create the inverse boost function.
Telefunken offers an experienced applications and design team and a high performance SiGe process for superior signal conditioning solutions.
