Features DC - 3.125 Gbps low jitter, high noise immunity, low power operation On-chip 100 Ω input and output termination minimizes insertion and return losses, reduces component count and minimizes board space 7 kV ESD on LVDS I/O pins protects adjoining components Small 3 mm x 3 mm LLP-8 space saving package Description The DS25BR150 is a single channel 3.125 Gbps LVDS buffer optimized for high-speed signal transmission over printed circuit boards and balanced cables. Fully differential signal paths ensure exceptional signal integrity and noise immunity. The DS25BR150 is a buffer/repeater with very low power consumption. Other LVDS devices with similar IO characteristics and with signal conditioning features include the following products. The DS25BR110 features four levels of equalization for use as an optimized receiver device, the DS25BR120 features four levels of pre-emphasis for use as an optimized driver device, while the DS25BR100 features both pre-emphasis and equalization for use as an optimized repeater device. Wide input common mode range allows the receiver 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. The differential inputs and outputs are internally terminated with a 100Ω resistor to lower device input and output return losses, reduce component count, and further minimize board space. Applications Clock or data buffering / repeating OC-48 / STM-16 Clock or data buffering / repeating InfiniBand FireWire

Reliability Metrics

DS25BR150TSD	BICMOS8B+	0	3632	0	0	2762292	2	783807897
DS25BR150TSDX	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.
