DESCRIPTION

· The NB7HQ14M is a high-performance differential 1:4 CML fanout buffer with a selectable Equalizer receiver.

· It compensates for degraded signals in Clock/Data paths up to 7 GHz or 10 Gb/s, outputting four identical CML copies.

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

· Features an Equalizer Enable pin (EQEN) to control signal flow through or bypass the Equalizer.

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

FEATURES

· Input Data Rate > 10 Gb/s.

· Input Clock Frequency > 7 GHz.

· 150 ps Typical Propagation Delay.

· 35 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 = 2.375 V to 2.625 V, VCCO = 1.71 V to 2.625 V.

· Internal Input Termination Resistors, 50 Ω.
