Description  
1
The NB6HQ14M 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 5 GHz or 6.5 Gb/s, respectively, the  
NB6HQ14M 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, NB6HQ14M  
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  
NB6HQ14M 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.
