MARKING

Description

The NB3N853531E is a low skew 3.3 V supply 1:4 clock

distribution fanout buffer. An input MUX selects either a

Fundamental Parallel Mode Crystal or a LVCMOS/LVTTL Clock by

using the CLK_SEL pin (HIGH for Crystal, LOW for Clock) with

LVCMOS / LVTTL levels.

The single ended CLK input is translated to four LVPECL Outputs.

Using the crystal input, the NB3N853531E can be a Clock Generator.

A CLK_EN pin can enable or disable the outputs synchronously to

eliminate runt pulses using LVCMOS/LVTTL levels (HIGH to enable

outputs, LOW to disable outputs).
