DS90LV110AT
1 to 10 LVDS Data/Clock Distributor with Failsafe
General Description
DS90LV110A 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 transmission for
point-to-point interconnects. This device can be used as a
high speed differential 1 to 10 signal distribution / fanout re-
placing multi-drop bus applications for higher speed links with
improved signal quality. It can also be used for clock distribu-
tion up to 200MHz.
The DS90LV110A accepts LVDS signal levels, LVPECL lev-
els directly or PECL with attenuation networks.
The LVDS outputs can be put into TRI-STATE® by use of the
enable pin.
For more details, please refer to the Application Information
section of this datasheet.
