NBSG14MNR2G

Clock Buffers, Drivers Overview

The NBSG14MNR2G is a 1-to-4 clock/data distribution chip from onsemi, optimized for ultra-low skew and jitter. It features Reduced Swing ECL (RSECL) outputs with a 400 mV peak-to-peak amplitude. The device accepts NECL, PECL, LVTTL, LVCMOS, CML, or 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 input frequencies up to 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 a QFN-16 package.

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'MN' corresponds to the QFN-16 package and 'R2' indicates tape and reel packaging containing 3000 units. Confirm RoHS compliance status associated with the specific suffix if required by procurement specifications.

Clock Buffers, Drivers Selection Notes

Select this component when low skew and jitter are critical for high-frequency clock distribution. Ensure the design accommodates the RSECL output voltage levels and appropriate termination voltages (VTT = VCC - 2 V for QFN). Verify thermal requirements against the junction-to-ambient resistance values provided in the datasheet.
