8P34S2102
Datasheet
Dual 1:2 LVDS Output 1.8V Fanout
Features
Description
▪ Dual 1:2 low skew, low additive jitter LVDS fanout buffers
The 8P34S2102 is a high-performance, low-power, differential
dual 1:2 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.
▪ Matched AC characteristics across both channels
▪ High isolation between channels
▪ Low power consumption
Two independent buffer channels are available. Each channel has
two 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 8P34S2102 ideal for
those clock distribution applications demanding well-defined
performance and repeatability.
▪ 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: 8ps typical
▪ Output skew: 10ps typical
▪ Low additive phase jitter, RMS: 45fs typical
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.
(fREF = 156.25MHz, 12kHz - 20MHz)
▪ Full 1.8V supply voltage mode
▪ Device current consumption (IDD): 76mA typical
▪ Lead-free (RoHS 6), 16-lead VFQFN packaging
▪ -40°C to 85°C ambient operating temperature
▪ Supports case temperature up to 105°C
