NB6HQ14M
2.5V 5GHz / 6.5Gbps
Differential Input to 1.8V /
2.5V 1:4 CML Clock / Data
Fanout Buffer w/ Selectable
Input Equalizer
Multi−Level Inputs w/ Internal Termination
Description
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 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.
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
www.DatfaoSrhleoewt4Uou.ctopmut skew applications.
The NB6HQ14M is a member of the ECLinPS MAX™ family of
high performance clock products.

NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared
operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit
values are applied individually under normal operating conditions and not valid simultaneously.
5. Input parameters vary 1:1 with VCC. Output parameters vary 1:1 with VCCO.
6. CML outputs loaded with 50 W to VCCO for proper operation.
7. Vth, VIH, VIL,, and VISE parameters must be complied with simultaneously.
8. Vth is applied to the complementary input when operating in single−ended mode.
9. VIHD, VILD, VID and VCMR parameters must be complied with simultaneously.
10. VCMR min varies 1:1 with GND, VCMR max varies 1:1 with VCC. The VCMR range is referenced to the crosspoint side of the differential input
signal.
