Description
The NB7VQ14M is a high performance differential 1:4 CML fanout
buffer with a selectable Equalizer receiver. When placed in series with
a Clock /Data path operating up to 8 GHz or 14 Gb/s, respectively, the
NB7VQ14M inputs will compensate the degraded signal transmitted
across a FR4 PCB backplane or cable interconnect and output four
identical CML copies of the input signal with a 1.8 V, 2.5 V or 3.3 V
power supply. 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 IN/IN 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 IN/IN inputs bypass the Equalizer. When
EQEN is set High, the IN/IN inputs flow through the Equalizer. The
default state at startup is LOW. As such, NB7VQ14M 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
NB7VQ14M to accept various logic level standards, such as LVPECL,
CML or LVDS. The 1:4 fanout design was optimized for low output
skew applications.
The NB7VQ14M is a member of the GigaComm
family of high
performance clock products.
