8P34S2106A
Dual 1:6 LVDS Output 1.8V / 2.5V Fanout Buffer
The 8P34S2106A is a high-performance, low-power,
differential dual 1:6 LVDS output 1.8V/2.5V fanout
buffer. The device supports fail-safe operation and 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.
Features
▪ Dual 1:6 low skew, low additive jitter LVDS fanout
buffers
▪ Matched AC characteristics across both channels
▪ High isolation between channels
▪ Low power consumption
▪ Both differential CLKA, nCLKA and CLKB, nCLKB
inputs accept LVDS, LVPECL and single-ended
LVCMOS levels
Guaranteed output-to-output and part-to-part skew
characteristics make the 8P34S2106A 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.
