Datasheet

Description

▪ Dual 1:4 low skew, low additive jitter LVDS fanout buffers

The 8P34S2104 is a high-performance, low-power, differential

dual 1:4 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 four 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 8P34S2104 ideal for those clock distribution

▪ 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: 8ps typical

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.

▪ Output skew: 10ps typical

▪ Low additive phase jitter, RMS: 45fs typical

(f_REF= 156.25MHz, 12kHz - 20MHz)

▪ Full 1.8V supply voltage mode

▪ Device current consumption (I_DD): 135mA typical

▪ Lead-free (RoHS 6), 28-lead VFQFN packaging

▪ -40°C to 85°C ambient operating temperature

▪ Supports case temperature up to 105°C
