✦ AI Summary
As AI workloads increase, data center operators are facing issues such as power instability, a lack of real-time monitoring, and signal degradation, which can lead to downtime.
TI unveiled and demonstrated 3 solutions, including ADC34DSO75, LMI800PS, and LMK6B, at the OCP Global Summit.
These solutions aim to improve data center reliability and efficiency with nanosecond-level telemetry, 800V isolated hot-swap power protection, and 9.6 fs jitter performance at 625 MHz.
As AI workloads grow rapidly, data center operators are facing challenges such as power instability, a lack of real-time monitoring, and signal degradation. These issues can lead to unexpected downtime.
To address this, Texas Instruments (TI) unveiled the ADC "ADC34DSO75" at the Open Compute Project (OCP) Global Summit. TI said the new ADC and its range of analog solutions help support the challenges of scaling AI infrastructure.
TI will demonstrate 3 solutions at the OCP Global Summit. The purpose of the 3 solutions is to improve data center reliability and efficiency.
The demonstrations consist of nanosecond-level real-time telemetry, stable high-voltage power delivery, and signal integrity based on ultra-low jitter.
TI described the ADC34DSO75 as a high-performance ADC. The product is characterized by a 3 GSPS sampling rate and the combination of ultra-fast sampling and on-chip digital signal processing in a small form factor.
Based on this architecture, the ADC34DSO75 supports nanosecond resolution and nanosecond-level monitoring speeds, enabling 24/7 low-power, event-based remote monitoring, TI said. It also said the device supports monitoring performance improvement by several thousand times compared with existing solutions by detecting transient fault events in real time and providing complete remote event-based telemetry.
According to TI, the product was designed to eliminate the need for on-site debugging and oscilloscopes, and it focuses on minimizing downtime through continuous monitoring of low-voltage, high-current power rails and high resolution. TI added that downtime losses can amount to hundreds of thousands of dollars per hour.
In addition, the ADC34DSO75 provides features that help optimize grid power efficiency, and TI said it achieves a smaller size and lower cost than existing monitoring methods. Through this, it said the product helps provide high-performance remote diagnostics for hyperscalers.
The LMI800PS is an 800V isolated hot-swap controller. Traditional discrete solutions required 5 ICs, but the LMI800PS integrates them into a single high-density package. This provides inrush current protection and power-path protection.
The LMI800PS includes an isolated bias supply and PMBus telemetry as integrated elements. As a result, it reduces board space by more than 60% and simplifies high-voltage design.
It also meets safety requirements based on 5kVrms reinforced isolation performance and a creepage distance of 8 mm or more. This supports safe power connections and rapid fault isolation.
As a result, it helps prevent individual load failures from spreading across the entire shared power bus, contributing to improved data center stability. It also supports ±400V and 800V distribution, making it a scalable solution that can be applied to a range of rack architectures and supporting the establishment of high-efficiency power systems for next-generation AI infrastructure.
The LMK6B is an oscillator based on bulk acoustic wave (BAW) technology, and it offers best-in-class jitter performance and excellent power-supply rejection ratio (PSRR).
Based on 9.6 fs jitter performance at 625 MHz, the LMK6B provides reliable performance for next-generation AI networking infrastructure and maintains signal integrity.
Kartik Vasanth, vice president and general manager of TI's Data Converters and Clocks business, said that as AI workloads increase, the need for real-time visibility and architectural stability is expanding. He said TI provides high-speed telemetry, advanced power protection, and precision timing solutions, helping hyperscalers and operators optimize next-generation AI data center performance and minimize downtime.
