Datasheet
Description
Features
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.
▪ 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
▪ Maximum input clock frequency: 2GHz
▪ Output amplitudes: 350mV, 500mV (selectable)
▪ Output bank skew: 10ps typical
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.
▪ Output skew: 20ps typical
▪ Low additive phase jitter, RMS: 45fs typical
(fREF = 156.25MHz, 12kHz – 20MHz)
▪ Full 1.8V and 2.5V supply voltage mode
▪ Device current consumption (IDD):
— 210mA typical: 1.8V
