Mixed-Signal Devices launches compact programmable oscillator supporting data center frequencies

Mixed-Signal Devices has announced the MS1180, a miniature oscillator engineered for next-generation networking and data center hardware. The device, supplied in a 2.0 × 1.6 mm package, supports common Ethernet and PCIe reference frequencies, including 156.25 MHz, 312.5 MHz, 491.52 MHz, and 625 MHz. The MS1180’s compact footprint and low RMS phase jitter make it suited for use in optical modules, network interface cards, and high-density interconnects where signal integrity and board area are limiting factors.

Built on the company’s CMOS-based “Virtual Crystal” architecture, the MS1180 combines frequency programmability with sub-hertz tuning resolution and femtosecond-level jitter performance. This approach provides the precision and phase noise characteristics required in high-speed serial communication systems.

The oscillator maintains ±20 ppm frequency stability from -40°C to +105°C and exhibits strong power-supply noise rejection, ensuring stable operation in thermally and electrically noisy environments typical of dense, high-speed designs.

According to the company, the MS1180 extends its portfolio of timing components for high-bandwidth, AI-centric infrastructure and allows system designers to simplify clock architectures while preserving synchronization accuracy across distributed data paths. Typical target applications include AI accelerators, optical transceivers, and edge computing modules.

Engineering samples are available now, with volume production scheduled for early 2026.
