Description
The NB7VQ58M is a high performance differential 2to1 Clock or
Data multiplexer with a selectable Equalizer receiver. When placed in
series with a Clock /Data path operating up to 7 GHz or 10.7 Gb/s,
respectively, the NB7VQ58M inputs will compensate the degraded
signal transmitted across an FR4 PCB backplane or cable
interconnect. Therefore, the serial data rate is increased by reducing
InterSymbol Interference (ISI) caused by losses in copper
interconnect or long cables.
The EQualizer ENable pin (EQEN) allows the INn/INn inputs to
either flow through or bypass the Equalizer section. Control of the
Equalizer function is realized by setting EQEN; When EQEN is set
Low, the INn / INn inputs bypass the Equalizer. When EQEN is set
High, the INn / INn inputs flow through the Equalizer. The default
state at startup is LOW. As such, the NB7VQ58M is ideal for SONET,
GigE, Fiber Channel, Backplane and other Clock/Data distribution
applications.
The differential inputs incorporate internal 50
W termination
resistors that are accessed through the VT pin. This feature allows the
NB7VQ58M to accept various logic level standards, such as LVPECL,
CML or LVDS.
The NB7VQ58M produces minimal Clock or Data jitter operating
up to 7 GHz or 10.7 Gb/s, respectively.
The 16 mA differential CML outputs provide matching internal
50
W terminations and 400 mV output swings when externally
terminated with a 50
W resistor to VCC.
The NB7VQ58M is offered in a low profile 3mm x 3 mm 16pin
QFN package and is a member of the GigaComm
family of high
performance Clock / Data products. Application notes, models, and
support documentation are available at www.onsemi.com.
