3.3V 2.7Gb/s Dual
Differential Clock/Data 2 x 2
Crosspoint Switch with
CML Output and Internal
Termination
Description
The NB4N840M is a high
bandwidth fully differential dual
2 x 2 crosspoint switch with CML inputs/outputs that is suitable for
applications such as SDH/SONET DWDM and high speed switching.
Fully differential design techniques are used to minimize jitter
accumulation, crosstalk, and signal skew, which make this device
ideal for loop
through and protection channel switching applications.
Each 2 x 2 crosspoint switch can fan
out and/or multiplex up to
2.7 Gb/s data and 2.7 GHz clock signals.
Internally terminated differential CML inputs accept AC
coupled
LVPECL (Positive ECL) or direct coupled CML signals. By providing
internal 50
input and output termination resistor, the need for
external components is eliminated and interface reflections are
minimized. Differential 16 mA CML outputs provide matching
internal 50 terminations, and 400 mV output swings when
externally terminated, 50 to V
CC
.
Single
ended LVCMOS/LVTTL SEL inputs control the routing of
the signals through the crosspoint switch which makes this device
configurable as 1:2 fan
out, repeater or 2 x 2 crosspoint switch. The
device is housed in a low profile 5 x 5 mm 32
pin QFN package.
