SiTime Corp. has rolled out a family of clock generators targeted for artificial intelligence (AI) data center applications.

These microelectromechanical systems (MEMS)-based clock system-on-chip (ClkSoC) offers a 10 times higher performance compared to standalone oscillators and clocks, SiTime said.

Called Chorus, the family of clock generators includes the clock, oscillator and resonator technologies in one integrated chip that can accelerate design time by up to six weeks. The clock generators can reduce the board area for timing by up to 50% by replacing up to four standalone oscillators, SiTime said.

“Before Chorus, hardware designers had to use discrete product types, such as clocks, oscillators and resonators, which resulted in performance compromises,” said Piyush Sevalia, executive vice president of marketing at SiTime. “Chorus delivers integrated clock generators to solve these problems and is yet another example of how we are transforming the timing market with our unique approach.”

Other features include:

  • Up to 10 times better resilience with integrated MEMS resonator
  • Smaller footprint
  • Low RMS phase jitter
  • Programmable frequency from 1 MHz to 700 MHz
  • Up to four differential (LVPECL, LVDS, LPHCSL) or eight LVCMOS outputs
  • Programmable, 1.8 V, 2.5 V or 3.3 V.
  • FlexSwing output reduces power consumption and eliminates termination resistors
  • ±20 ppm and ±50 ppm from -40° C to 105° C.
  • Configurable spread-spectrum clock generation
  • PCIe standard generation 1 to 6 support
  • Clock fault monitors
