Features DC - 3.125 Gbps low jitter, low skew, low power operation Pin configurable, fully differential, non-blocking architecture Pin selectable transmit pre-emphasis and receive equalization eliminate data dependant jitter Wide Input Common Mode Voltage Range allows DC-coupled interface to CML and LVPECL drivers On-chip 100Ω input and output termination minimizes insertion and return losses, reduces component count and minimizes board space 8 kV ESD on LVDS I/O pins protects adjoining components Small 4 mm x 4 mm LLP-16 space saving package Description The DS25CP102 is a 3.125 Gbps 2x2 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 DS25CP102 features two levels (Off and On) of transmit pre-emphasis (PE) and two levels (Off and On) of receive equalization (EQ). 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 insertion and return losses, reduce component count and further minimize board space. Applications High-speed channel select applications Clock and data buffering and muxing OC-48 / STM-16 SD/HD/3GHD SDI Routers

DS25CP102TSQ	BICMOS8B+	0	3632	0	0	2762292	2	783807897
DS25CP102TSQX	BICMOS8B+	0	3632	0	0	2762292	2	783807897

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.
