NB3RL02FCT2G

Clock Buffers, Drivers Overview

The NB3RL02FCT2G is a low-skew, low-jitter 1:2 clock fanout buffer designed for portable equipment. It features an integrated Low-Drop-Out (LDO) voltage regulator that accepts input voltages from 2.3 V to 5.5 V and provides a regulated 1.8 V output at up to 50 mA. The device operates with frequencies up to 80 MHz and supports both LVCMOS and sinusoidal inputs. Key electrical specifications include −149 dBc/Hz phase noise at a 10 kHz offset and 0.37 ps RMS additive jitter. It utilizes an adaptive clock output buffer with controlled slew rates to minimize EMI emissions.

Clock Buffers, Drivers Feature Summary

• Low additive noise performance with 0.37 ps RMS output jitter
• Adaptive output buffers with limited slew rate (1 ns to 5 ns) for EMI reduction
• Supports operation up to 80 MHz with independent clock request control

Clock Buffers, Drivers Applications

• Cellular phones
• Global Positioning Systems (GPS)
• Mobile WLAN transceivers

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix FCT2G corresponds to the WLCSP8 package and tape & reel shipping configuration. Confirm RoHS compliance status as indicated by the Pb-Free designation in the ordering information section of the datasheet.

Clock Buffers, Drivers Selection Notes

Select this component when a compact solution is required for buffering clocks in battery-powered devices. The integrated LDO simplifies design by powering the source clock directly. Ensure the application load capacitance falls between 10 pF and 50 pF to maintain specified rise and fall times.
