. The company's new products aim to deliver the essential capabilities needed to power, monitor, and optimize next-generation AI data centers.

ADC34DSO75 Delivers Nanosecond-Level Telemetry for Real-Time Fault Detection

The ADC34DSO75 represents the industry's highest performance 3 gigasamples per second analog-to-digital converter, enabling 24/7, low-power, event-based remote monitoring at nanosecond resolution—thousands of times faster than what current solutions offer1

. Existing monitoring solutions often fail to detect the nanosecond-level power-rail glitches that cause costly downtime in AI data centers. By combining ultra-high-speed sampling with advanced on-chip digital signal processing in a small form factor, the ADC34DSO75 detects and captures transient fault events in real time2

. This compact solution offers hyperscalers unmatched remote diagnostic capabilities at a fraction of the size and cost of conventional monitoring methods.

LMI800PS Simplifies High-Voltage Power Delivery Architecture

The LMI800PS serves as the industry's first 800V isolated hot-swap controller, replacing a complex discrete solution requiring five integrated circuits with a single high-density package that delivers in-rush current and power path protection2

.

The LMI800PS enables safe power insertion and fast fault isolation, meeting safety standards with 5kVrms reinforced isolation and more than 8mm creepage3

3

. This prevents a single load failure from disrupting the shared power bus and maximizes data center stability. Supporting both ±400V and 800V distributions, the device provides a scalable solution for diverse rack architectures, accelerating the deployment of high-efficiency power systems required for next-generation AI infrastructures1

LMK6B Oscillator Preserves Signal Integrity at Extreme Speeds

The LMK6B is a bulk acoustic wave-based oscillator that delivers best-in-class jitter performance and power-supply rejection ratio2

2

. As data center transmission rates approach 3.2Tbps, the margin for timing error shrinks significantly, and even minute jitter can increase bit error rates and cause system instability3

3

. The LMK6B provides industry-leading ultra-low jitter performance of 9.6 femtoseconds at 625MHz, ensuring reliable performance and helping preserve signal integrity for AI-driven networking infrastructures1
