SiTime Corporation introduced its Chorus family of clock generators for AI datacenter applications. This new MEMS-based clock-system-on-a-chip (ClkSoC) family offers 10X higher performance in half the size, compared to standalone oscillators and clocks. Chorus' new approach includes clock, oscillator and resonator technologies in an integrated chip, simplifying system clock architecture and accelerating design time by up to six weeks.

Chorus, combined with recently acquired timing products from Aura Semiconductor, builds on strategy to offer a complete portfolio of highly differentiated solutions. Rapid upgrade cycles for AI hardware will be essential to running data and compute-intensive AI workloads. Chorus, with its integrated MEMS resonator, addresses the limitations of legacy clock generators, eliminating problems such as noise and matching the resonator's impedance with the clock.

Also, Chorus can reduce the board area for timing by up to 50% by replacing up to four standalone oscillators. Flexible Frequency: Programmable frequency from 1 MHz to 700 MHz. Flexible Output Types: Up to four differential (LVPECL, LVDS, LPHCSL) or eight LVCMOS outputs.

Flexible Supply Voltage: Programmable, 1.8V, 2.5V, or 3.3V. Reduced Power and Simplified Circuitry: FlexSwing output reduces power consumption and eliminates termination resistors. Excellent Frequency Stability: +-20 ppm and +-50 ppm from -40degC to 105degC.

EMI Reduction: Configurable spread-spectrum clock generation. Compliant with the Latest PCIe Standard: Generation 1 to 6. Enhanced System Robustness: Clock fault monitors (Lock Loss). Availability: SiTime's Chorus family of clock generators is sampling to strategic customers now, with general sampling availability in second half 2024.
