DS25CP104ATSQ/NOPB

The DS25CP104ATSQ/NOPB is a 3.125Gbps 4x4 LVDS Crosspoint Switch optimized for high speed signal routing and switching over lossy FR-4 printed circuit board backplanes and balanced cables. Fully differential signal paths ensure exceptional signal integrity and noise immunity. The non-blocking architecture allows connections of any input to any output or outputs. The switch configuration can be accomplished via external pins or the System Management Bus (SMBus) interface. The DS25CP104A feature four levels (off, low, medium, high) of transmit pre-emphasis (PE) and four levels (off, low, medium, high) of receive equalization (EQ) settable via the SMBus interface. Off and medium PE levels and off and low EQ levels are settable with the external pins. In addition, the SMBus circuitry enables the loss of signal (LOS) monitors that can inform a system of the presence of an open inputs condition (e.g. disconnected cable).
