DESCRIPTION

· The NB7VQ14M is a high-performance differential 1:4 CML fanout buffer with a selectable Equalizer receiver.

· It compensates degraded signals transmitted across FR4 PCB backplanes or cable interconnects, operating up to 8 GHz or 14 Gb/s.

· Outputs four identical CML copies of the input signal with a 1.8 V, 2.5 V, or 3.3 V power supply.

· Reduces Inter-Symbol Interference (ISI) caused by losses in copper interconnects or long cables.

· Features an Equalizer Enable pin (EQEN) to control the Equalizer function.

FEATURES

· Input Clock Frequency > 8 GHz, Typical.

· 165 ps Typical Propagation Delay.

· 30 ps Typical Rise and Fall Times.

· < 15 ps Maximum Output Skew.

· < 0.8 ps Maximum RMS Clock Jitter.

· < 10 ps pp of Data Dependent Jitter.

· Differential CML Outputs, 400 mV Peak-to-Peak, Typical.

· Selectable Input Equalization.

· Operating Range: VCC = 1.71 V to 3.6 V with GND = 0 V.

· Internal Input Termination Resistors, 50 Ω.

· -40°C to +85°C Ambient Operating Temperature.

· Pb-Free Devices.

APPLICATIONS

· Ideal for SONET, GigE, Fiber Channel, Backplane, and other Clock/Data distribution applications.
