Product Overview
NB6VQ572M: Input Mux - 4:1 Differential, 1.8 V / 2.5 V, with Input
Equalization, Clock / Data Fanout Buffer - 1:2 CML
For complete documentation, see the data sheet
Product 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 5GHz / 6.5Gbps respectively with a 1.8V or 2.5V 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-ohm 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 400mV
when externally loaded and terminated with a 50 ohm resistor to VCC and are optimized for low skew and minimal jitter. The
NB6VQ572M is offered in a low profile 5x5 mm 32-pin QFN Pb-Free package. Application notes, models, and support
documentation are available at www.onsemi.com. The NB6VQ572M is a member of the ECLinPS MAX family of high performance
clock products.
