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.
