3.3V Differential 1:21
Differential Fanout Clock
Driver with HCSL level
Output
Description
The NB4N121K is a Clock differential input fanout distribution 1 to
21 HCSL level differential outputs, optimized for ultra low
propagation delay variation. The NB4N121K is designed with HCSL
clock distribution for FBDIMM applications in mind.
Inputs can accept differential LVPECL, CML, or LVDS levels.
Singleended LVPECL, CML, LVCMOS or LVTTL levels are
and 13). Clock input pins incorporate an internal 50
W on die
termination resistors.
Output drive current at IREF (Pin 1) for 1X load is selected by
connecting to GND. To drive a 2X load, connect IREF to VCC. See
Figure 9.
The NB4N121K specifically guarantees low output–to–output
skews. Optimal design, layout, and processing minimize skew within
a device and from device to device. System designers can take
advantage of the NB4N121K’s performance to distribute low skew
clocks across the backplane or the motherboard.
