NBSG14BAR2

Clock Buffers, Drivers Overview

The NBSG14BAR2 is a 1-to-4 differential clock/data driver manufactured by onsemi, utilizing SiGe technology. It features Reduced Swing ECL (RSECL) outputs with a 400 mV peak-to-peak amplitude. The device accepts NECL, PECL, LVTTL, LVCMOS, CML, and LVDS inputs via internal 50 Ω termination resistors. Operating at VCC = 2.375 V to 3.465 V (VEE = 0 V) or VEE = -2.375 V to -3.465 V (VCC = 0 V), it supports maximum frequencies of 12 GHz and data rates up to 12 Gb/s. Typical propagation delay is 125 ps, with rise/fall times of 30 ps. It is housed in an FCBGA-16 package.

Clock Buffers, Drivers Procurement Notes

Verify the specific 'BA' suffix indicates the FCBGA-16 package configuration. Confirm that the 'R2' suffix corresponds to the tape and reel shipping format containing 100 units per reel as listed in the ordering information. Ensure compatibility with the required thermal management for the BGA package.

Clock Buffers, Drivers Selection Notes

Select this component when a 1-to-4 fanout buffer with ultra-low skew is required. Choose between the BA (FCBGA-16) and MN (QFN-16) packages based on board space and thermal requirements. Verify input signal standards match the supported list, noting that single-ended inputs require specific biasing configurations.

Clock Buffers, Drivers Part Context

This part belongs to the NBSG14 family of SiGe differential drivers. The NBSG14BAR2 specifically denotes the FCBGA-16 package variant supplied in a tape and reel. Other variants include the QFN-16 package (MN suffix). The device is designed for high-frequency applications where signal integrity is critical.

Clock Buffers, Drivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative 1:4 differential clock drivers from other manufacturers only if they meet the specific RSECL output swing and input termination requirements.
