Description
The NB7HQ14M 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 7 GHz or 10 Gb/s, respectively, the
NB7HQ14M 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. 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, NB7HQ14M
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
NB7HQ14M to accept various logic level standards, such as LVPECL,
CML or LVDS. The outputs have the flexibility of being powered by
either a 2.5 V or 1.8 V supply. The 1:4 fanout design was optimized
for low output skew applications.
The NB7HQ14M is a member of the GigaComm
family of high
performance clock products.
