NBSG14MNG

Clock Buffers, Drivers Overview

The NBSG14 is a 1-to-4 clock/data distribution chip optimized for ultra-low skew and jitter. It accepts NECL, PECL, LVTTL, LVCMOS, CML, or LVDS inputs via internal 50 Ohm termination resistors. Outputs are RSECL (Reduced Swing ECL) with a 400 mV peak-to-peak differential swing. The device supports a maximum input clock frequency of 12 GHz and data rates up to 12 Gb/s. Operating ranges include VCC = 2.375 V to 3.465 V with VEE = 0 V, or VCC = 0 V with VEE = -2.375 V to -3.465 V. Typical propagation delay is 125 ps, with rise/fall times of 30 ps.

Clock Buffers, Drivers Procurement Notes

Verify the specific package suffix required for the application: BA for FCBGA-16 or MN for QFN-16. Confirm Pb-free status if mandated by environmental regulations. Ensure power supply configurations match the datasheet requirements for either positive VCC or negative VEE operation. Check thermal resistance specifications against board airflow conditions.

Clock Buffers, Drivers Selection Notes

Select the BGA package for applications requiring lower thermal resistance at 500 lfpm airflow, noting its 70°C max operating temperature. Choose the QFN package for higher temperature tolerance up to 85°C. Verify that output termination voltages align with the specific package recommendations (VCC - 1.5 V for BGA, VCC - 2 V for QFN). Ensure input signals fall within the specified common mode range.

Clock Buffers, Drivers Part Context

The NBSG14 belongs to onsemi's SiGe differential driver family, designed for high-frequency clock and data distribution. It serves as a fanout buffer converting single-ended or differential inputs into four low-skew differential outputs. The device integrates internal termination to simplify PCB layout and reduce component count in high-speed designs.
