Mixed Signal Devices has unveiled a next-generation clock and timing portfolio to deliver high-performance timing solutions for complex and high-speed computing and communications systems. Two new families, the MS11X0 oscillator and MS15X0 jitter attenuator, provide femtosecond-level jitter, low phase noise, and exceptional thermal stability, with no programmability or power efficiency penalty, according to the company.

The MS1130 and MS1150 oscillators and the MS1500 and MS1510 jitter attenuators are optimized for applications such as GPU fabrics in AI servers, 5G fronthaul and mid-haul synchronization, precision radar systems, and high-speed SerDes interfaces.
The challenge is that traditional analog-based timing solutions can’t keep pace with the stability and scalability demands of advanced applications, said Mixed Signal Devices. Current demands include rugged, ultra-low-jitter timing solutions that maintain stability under extreme thermal and voltage conditions while offering seamless programmability and integration.
To meet these challenges, the timing platform is built on 28-nm CMOS technology and the company’s patented Virtual Crystal architecture. Offer a range of integration-ready footprints and factory-configurable outputs, these solutions simplify clock tree design, reduce component counts, and streamline system integration, the company said.
1-GHz and 2-GHz oscillators
The new timing portfolio includes the MS1130 1-GHz and the MS1150 2-GHz oscillators that deliver sub-20 fs jitter, ±20-ppm thermal stability, and programmable configuration in compact CMOS packages. The MS1130 is optimized for 800G networking and AI compute fabrics, while the MS1150 is designed for ultra-low-jitter system clocks and timing cleanup in complex architectures.
The ultra-low-jitter (down to 19 fs RMS) provides clean stable signals for SerDes, memory interfaces, and optical transceivers, and the ±20-ppm thermal stability (–40°C to +105°C) delivers reliable performance in harsh conditions. The compact CMOS package (as small as 2.5 × 2.0 mm) supports easy integration into space-constrained and power-sensitive platforms. Programmable output configuration supports factory-programmed frequency, voltage, and output format for flexible design integration.
1-GHz and 2-GHz jitter attenuators
The MS1500 1-GHz and MS1510 2-GHz jitter attenuators offer femtosecond-level jitter, advanced power supply noise rejection, and robust thermal resilience. The MS1500 supports up to 1-GHz output for PCIe and Ethernet clock cleanup, while the MS1510 performance of 2 GHz targets coherent optics, SerDes links, and advanced AI platforms. The jitter attenuators simplify clock tree architectures and enable cleaner signal performance across increasingly complex platforms.
Key features include ultra-low-jitter performance of 35-fs RMS for the MS1500 and 25 fs RMS (12 kHz–20 MHz) for the MS1510; a programmable timing engine that includes a factory-configured NVM and an adaptive DSP that ensures precision across voltage and temperature variations; and environmental resilience with an operating temperature range of -40°C to 105°C and a high power-supply noise rejection.
A compact 3.2 × 2.5 mm LGA package simplifies layout in dense PCBs. Output formats support LVDS, CML, LVPECL, and HCSL. Low power operation is provided by a single 1.8-V supply with internal regulation.
The MS1130, MS1150, MS1500, and MS1510 clocks are currently sampling. They will be showcased at the IEEE MTT-S International Microwave Symposium (IMS), June 15-20, 2025, in San Francisco.
