Description

The 8P34S2106 is a high-performance, low-power, differential

dual 1:6 LVDS output 1.8V/2.5V 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/2.5V power supply. The integrated bias voltage references

enable easy interfacing of AC-coupled signals to the device

inputs.
