Features DC - 1.5 Gbps low jitter, low skew, low power operation Wide Input Common Mode Voltage Range allows for DC-coupled interface to LVDS, CML and LVPECL drivers Redundant inputs ^LOS circuitry detects open inputs fault condition Integrated 100Ω input and output terminations 8 kV ESD on LVDS I/O pins protects adjoining components Small 6 mm x 6 mm LLP-40 space saving package Description The DS10BR254 is a 1.5 Gbps 1:4 LVDS repeater optimized for high-speed signal routing and distribution over FR-4 printed circuit board backplanes and balanced cables. Fully differential signal paths ensure exceptional signal integrity and noise immunity. The device has two different LVDS input channels and a select pin determines which input is active. A loss-of-signal ( ^LOS) circuit monitors both input channels 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. Applications Clock distribution Clock and data buffering and muxing OC-12 / STM-4 SD/HD SDI Routers

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
DS10BR254TSQ	BICMOS8B+	0	3632	0	0	2762292	2	783807897
DS10BR254TSQX	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.
