NBSG14MN

Clock Buffers, Drivers Overview

The NBSG14 is a 2.5V/3.3V SiGe differential 1-to-4 clock/data driver with RSECL outputs, optimized for ultra-low skew and jitter. It accepts NECL, PECL, LVTTL, LVCMOS, CML, or LVDS inputs via internal 50 Ω termination resistors. Outputs provide 400 mV peak-to-peak differential RSECL signals. Maximum input frequency reaches 12 GHz typical, with propagation delay of 125 ps typical. Operating voltage ranges from 2.375 V to 3.465 V for positive supply configurations.

Clock Buffers, Drivers Feature Summary

• Maximum input clock frequency up to 12 GHz typical
• Ultra-low skew: within-device skew 6 ps typical, device-to-device skew 25 ps typical
• Internal 50 Ω input termination resistors for simplified interfacing
• Compatible with NECL, PECL, LVTTL, LVCMOS, CML, and LVDS input standards

Clock Buffers, Drivers Applications

• High-speed clock distribution networks
• Data communication systems requiring low jitter buffering
• Telecommunications infrastructure equipment

Clock Buffers, Drivers Procurement Notes

Verify package suffix (BA for FCBGA-16, MN for QFN-16) against design requirements. Confirm Pb-free status if required by environmental specifications. Ensure thermal management aligns with junction-to-ambient resistance values provided in the datasheet for the selected package type.

Clock Buffers, Drivers Selection Notes

Select BA suffix for flip-chip ball grid array packaging suitable for high-density boards. Choose MN suffix for quad flat no-lead packaging. Verify operating temperature range: BGA supports up to 70°C, while QFN supports up to 85°C. Ensure power supply decoupling meets the recommended layout guidelines for stable operation at 12 GHz.

Clock Buffers, Drivers Part Context

Part of onsemi's NB series of high-speed clock drivers. Designed for applications demanding precise timing alignment and minimal signal degradation across multiple output branches in high-frequency digital systems.

Clock Buffers, Drivers Replacement Considerations

NBSG14MNG is the Pb-free version of the QFN-16 package variant. NBSG14MNHTBG offers tape and reel packaging for the QFN-16 form factor. No direct functional equivalents are listed; verify pin compatibility and electrical parameters when considering alternative manufacturers.
