Dual 1:6 LVDS Output 1.8V Fanout Buffer
8P34S2106
Datasheet
Description
The 8P34S2106 is a high-performance, low-power, differential
dual 1:6 LVDS output 1.8V fanout buffer. The device is designed
for the fanout of high-frequency, very low additive phase-noise
clock and data signals. Two independent buffer channels are
available, each channel has six low skew outputs. High isolation
between channels minimizes noise coupling. AC characteristics
such as propagation delay are matched between channels.
Guaranteed output-to-output and part-to-part skew characteristics
make the 8P34S2106 ideal for those clock distribution
applications demanding well-defined performance and
repeatability. The device is characterized to operate from a 1.8V
power supply. The integrated bias voltage references enable easy
interfacing of AC-coupled signals to the device inputs.
