onsemi NB6L11DTG: A 3V Differential 1:2 CML Clock/Data Fanout Buffer

In the realm of high-speed data transmission and clock distribution, signal integrity is paramount. The onsemi NB6L11DTG stands out as a critical component engineered to address these challenges. This device is a differential 1:2 fanout buffer designed to operate from a single 3.3V power supply, making it highly suitable for modern low-voltage systems. It accepts differential Current Mode Logic (CML) input signals and provides two identical, low-skew copies of the input at its outputs, also in CML format.

The primary function of the NB6L11DTG is to fan out one high-speed input signal into two identical outputs with minimal added jitter and phase distortion. This capability is indispensable in applications such as high-frequency clock distribution networks, high-speed data routing, and telecommunications infrastructure, where preserving signal fidelity across multiple destinations is crucial. The device supports data rates up to 6 GHz, making it compatible with a wide array of demanding protocols and interfaces.

A key advantage of this buffer is its differential design, which offers superior noise immunity compared to single-ended solutions. By processing the difference between two complementary signals, it effectively rejects common-mode noise, a significant benefit in electrically noisy environments. Furthermore, the NB6L11DTG features very low additive phase jitter, which is essential for maintaining timing accuracy in high-speed synchronous systems. Its internal termination and optimized output design ensure clean signal edges and reduce reflections.

The device is offered in a compact TSSOP-8 package, facilitating its use in space-constrained PCB layouts. Its 3.3V operation aligns with contemporary system voltage standards, simplifying power supply design and reducing overall power consumption.
