File Size : 116 KB Manufacturer:ANPEC Description:The DS40MB200 is a signal conditioning 2:1 multiplexer and a 1:2 buffer designed to support port redundancy up to 4 Gb/s. Each input stage has a fixed equalizer that provides equalization to compensate about 5 dB of transmission loss from a short backplane trace (about 10 inches backplane). The output driver has pre-emphasis (driver-side equalization) to compensate the transmission loss of the backplane that it is driving. The driver conditions the output signal such that the lower frequency and higher frequency pulses reach approximately the same amplitude at the end of the backplane, and minimize the deterministic jitter caused by the amplitude disparity. The DS40MB200 provides 4 steps of user-selectable pre-emphasis ranging from 0, -3, -6 and C9 dB to handle different lengths of backplane. Figure 1 shows a driver pre-emphasis waveform. The pre-emphasis duration is 200ps nominal, corresponds to 0.75 bit-width at 4 Gb/s. The pre-emphasis levels of switch-side and line-side can be individually programmed. The high speed inputs are self-biased to about 1.5V and are designed for AC coupling. The inputs are compatible to most AC coupling differential signals such as LVDS, LVPECL and CML.
