DS25BR120 www.ti.com SNLS256E – MARCH 2007 – REVISED APRIL 2013 DS25BR120 3.125 Gbps LVDS Buffer with Transmit Pre-Emphasis Check for Samples: DS25BR120 FEATURES DESCRIPTION • The DS25BR120 is a single channel 3.125 LVDS buffer optimized for high-speed transmission over lossy FR-4 printed circuit backplanes and balanced metallic cables. differential signal paths ensure exceptional integrity and noise immunity. 1 2 • • • • DC - 3.125 Gbps Low Jitter, High Noise Immunity, Low Power Operation Four Levels of Transmit Pre-Emphasis Drive Lossy Backplanes and Cables On-Chip 100Ω 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 8-WSON Space Saving Package The DS25BR120 features four levels of pre-emphasis (PE) for use as an optimized driver device. Other LVDS devices with similar IO characteristics include the following products. The DS25BR110 features four levels of equalization for use as an optimized receiver device, while the DS25BR100 features both preemphasis and equalization for use as an optimized repeater device. The DS25BR150 is a buffer/repeater with the lowest power consumption and does not feature transmit pre-emphasis nor receive equalization. APPLICATIONS • • • Gbps signal board Fully signal Clock and Data Buffering Metallic Cable Driving FR-4 Driving 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 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.
