Description
The SL18861DI product is a high performance 3 output
clock distribution buffer and provides 3 outputs from a
single input clock by using SLI proprietary low phase
noise and low power dissipation circuit design.
The SL18861DI can be used in baseband mobile RF
applications including WLAN, Bluetooth and DVB-H as an
input clock reference. The product designed to isolate
each device driven by their clock outputs to minimize
interference between these devices.
Each of the clock buffer outputs can be individually
disabled by using OE1/2/3 control pins to reduce the
power consumption if the connected device does not need
the clock. The device operates from single power supply
from 1.70V to 3.65V and from -40 C to 85 C.
