Description

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 Inter−Symbol 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 start−up is LOW. As such, NB6HQ14M

is ideal for SONET, GigE, Fiber Channel, Backplane and other

Clock/Data distribution applications.

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.
