NB6LQ572M: 2.5 / 3.3 V Differential 4:1 Mux w/Input Equalizer to 1:2 CML
Clock/Data Fanout / Translator
For complete documentation, see the data sheet
Product Description
The NB6LQ572M is a high performance differential 4:1 Clock / Data input multiplexer and a 1:2 CML Clock / Data fanout buffer that
operates up to 6GHz / 8Gbps respectively with a 2.5V or 3.3V power supply. Each INx/INxb 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 NB6L572M, which is pin-compatible
to the NB6LQ572M. The differential Clock / Data inputs have internal 50-ohm termination resistors and will accept differential
LVPECL, CML, or LVDS logic levels. The NB6LQ572M 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 NB6LQ572M is ideal for SONET, GigE, Fiber
Channel, Backplane and other Clock/Data distribution applications. The two differential CML outputs will swing 400mV when
externally loaded and terminated with a 50-ohm resistor to VCC and are optimized for low skew and minimal jitter. The NB6LQ572M
is offered in a low profile 5x5mm 32-pin QFN Pb-Free package. The NB6LQ572M is a member of the ECLinPS MAX family of high
performance clock products.
