Features DC - 3.125 Gbps low jitter, low skew, low power operation Pin and SMBus configurable, fully differential, non-blocking architecture Pin (two levels) and SMBus (four levels) selectable pre-emphasis and equalization eliminate ISI jitter Wide Input Common Mode Range enables easy interface to CML and LVPECL drivers ^LOS circuitry detects open inputs fault condition On-chip 100Ω input and output termination minimizes insertion and return losses, reduces component count and minimizes board space. The DS25CP114 eliminates the on-chip input termination for added design flexibility. 8 kV ESD on LVDS I/O pins protects adjoining components Small 6 mm x 6 mm LLP-40 space saving package Description The DS25CP104A and DS25CP114 are 3.125 Gbps 4x4 LVDS crosspoint switches 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 and DS25CP114 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). 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. On the DS25CP104A each differential input and output is internally terminated with a 100Ω resistor to lower return losses, reduce component count and further minimize board space. For added design flexibility the 100Ω input terminations on the DS25CP114 have been eliminated. This enables a designer to build custom crosspoint configurations and distribution circuits that require a limited multidrop signaling topology.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
