DS90LV110T
1 to 10 LVDS Data/Clock Distributor
General Description
DS90LV110 is a 1 to 10 data/clock distributor utilizing LVDS
(Low Voltage Differential Signaling) technology for low
power, high speed operation. Data paths are fully differential
from input to output for low noise generation and low pulse
width distortion. The design allows connection of 1 input to
all 10 outputs. LVDS I/O enable high speed data transmis-
sion for point-to-point interconnects. This device can be used
as a high speed differential 1 to 10 signal distribution / fanout
replacing multi-drop bus applications for higher speed links
with improved signal quality. It can also be used for clock
distribution up to 400MHz.
The DS90LV110 accepts LVDS signal levels, LVPECL levels
directly or PECL with attenuation networks.
The LVDS outputs can be put into TRI-STATE by use of the
enable pin.

section of this datasheet.
