NB6VQ572M
1.8V / 2.5V Differential 4:1
Mux w/Input Equalizer to
1:2 CML Clock/Data Fanout /
Translator
MultiLevel Inputs w/ Internal Termination
Description
The NB6VQ572M is a high performance differential 4:1 Clock /
Data input multiplexer and a 1:2 CML Clock / Data fanout buffer that
operates up to 5 GHz / 6.5 Gbps respectively with a 1.8 V or 2.5 V
power supply.
Each INx / INx input pair incorporates a fixed Equalizer Receiver,
which when placed in series with a Clock / Data path, will enhance the
degraded signal transmitted across an FR4 backplane or cable
interconnect. For applications that do not require Equalization,
consider the NB7V572M, which is pincompatible to the
NB6VQ572M.
The differential Clock / Data inputs
have internal 50 W termination
resistors and will accept differential LVPECL, CML, or LVDS logic
levels. The NB6VQ572M incorporates a pair of Select pins that will
choose one of four differential inputs and will produce two identical
CML output copies of Clock or Data.
As such, the NB6VQ572M is ideal for SONET, GigE, Fiber
Channel, Backplane and other Clock/Data distribution applications.
The two differential CML outputs will swing 400 mV when externally
loaded and terminated with a 50
W resistor to VCC and are optimized
for low skew and minimal jitter.
The NB6VQ572M is offered in a low profile 5x5 mm 32pin QFN
PbFree package. Application notes, models, and support
is a member of the ECLinPS MAX
family of high performance
clock products.
