DS10BR150
1.0 Gbps LVDS Buffer / Repeater
General Description
The DS10BR150 is a single channel 1.0 Gbps LVDS buffer
optimized for high-speed signal transmission over lossy FR-4
printed circuit board backplanes and balanced cables. Fully
differential signal paths ensure exceptional signal integrity
and noise immunity.
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 out-
put return losses, reduce component count and further mini-
mize board space.
Features
■ DC - 1.0 Gbps low jitter, high noise immunity, low power
operation
■ 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-LLP space saving package
Applications
■ Clock and data buffering
■ OC-12 / STM-4
■ Fibre Channel (1GFC)
■ FireWire 800
