Descripción de DS25BR440
The DS25BR440 is a 3.125 Gbps Quad LVDS buffer optimized for high-speed signal routing and repeating over lossy FR-4 printed circuit board backplanes and balanced cables. Fully differential signal paths ensure exceptional signal integrity and noise immunity.
The DS25BR440 features two levels of transmit pre-emphasis (PE) and two levels of receive equalization (EQ). Both of these features compensate for interconnect losses and ultimately maximize noise margin. A loss-of-signal (LOS) circuit monitors each input channel and a unique LOS pin is asserted when no signal is detected at that input.
Wide input common mode range allows the switch to accept signals with LVDS, CML and LVPECL levels; the output levels are LVDS. A very small package footprint requires a minimal space on the board while the flow-through pinout allows easy board layout. Each differential input and output is internally terminated with a 100Ω resistor to lower device return losses, reduce component count and further minimize board space.
