Compact oscillator fits tight AI interconnects

Housed in a 6-pin, 2.0×1.6-mm LGA package, Mixed-Signal Devices’ MS1180 crystal oscillator conserves space in AI data center infrastructure. Factory-programmed to provide any frequency from 10 MHz to 1000 MHz with under 1-ppb resolution, it is well-suited for 1.6T and 3.2T optical modules, active optical cables, active electrical cables, and other size-constrained interconnect devices.

The MS1180 is optimized for key networking frequencies—156.25 MHz, 312.5 MHz, 491.52 MHz, and 625 MHz—and maintains low RMS phase jitter of 28.3 fs to 43.1 fs when integrated from 12 kHz to 20 MHz. It offers ±20-ppm frequency stability from –40 °C to +105 °C. Power-supply-induced phase noise is –114 dBc for 50-mV supply ripples at 312.5 MHz, with a supply-jitter sensitivity of 0.1 fs/mV (measured with 50-mVpp ripple from 50 kHz to 1 MHz on VDD pin).

Supporting multiple output formats (CML, LVDS, EXT LVDS, LVPECL, HCSL), the device runs from a single 1.8- V supply with an internal regulator.

The MS1180 crystal oscillator is sampling now to strategic partners and Tier 1 customers. Production volumes are expected to ramp in Q1 2026.
