NBSG14MNR2

Clock Buffers, Drivers Overview

The NBSG14MNR2G is a 1-to-4 clock and data distribution chip manufactured by onsemi, utilizing SiGe technology. It features Reduced Swing ECL (RSECL) outputs with a typical peak-to-peak amplitude of 400 mV. The device accepts NECL, PECL, LVTTL, LVCMOS, CML, or LVDS inputs via internal 50 Ω termination resistors. It supports maximum input frequencies up to 12 GHz and data rates up to 12 Gb/s. Electrical specifications include a typical propagation delay of 125 ps and rise/fall times of 30 ps. The component is housed in a QFN-16 package.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix for the desired packaging configuration. The 'MN' suffix indicates the QFN-16 package type. Confirm whether the 'G' suffix is required for lead-free compliance. Ensure the tape and reel quantity matches the production requirements, as standard reels contain 3000 units.

Clock Buffers, Drivers Selection Notes

Select this component when low jitter and skew are critical for high-frequency applications. Verify that the power supply voltage range (2.375 V to 3.465 V) aligns with the system design. Consider the thermal resistance characteristics of the QFN-16 package if operating at elevated temperatures or high duty cycles.

Clock Buffers, Drivers Part Context

This part belongs to the NBSG14 series of differential clock drivers. It is functionally similar to other members of the family but distinguished by its specific package and termination options. The QFN-16 variant offers a compact footprint suitable for dense PCB layouts compared to larger BGA packages.

Clock Buffers, Drivers Replacement Considerations

Direct replacements within the same family include the NBSG14BAHTBG (FCBGA-16 package). Cross-referencing pinouts and electrical parameters is essential when substituting different package types.
