MEMS oscillator supports timing with 70fs jitter
The component is based on SiTime’s third generation of MEMS technology and is suitable for clocking 100G to 800G optical modules. Other applications, including datacenter switches, telecom routers, edge servers, AI/graphics cards, and storage controllers.
The part supports networking frequencies from 25MHz to 644.5MHz with RMS phase jitter of 70 femtoseconds. It comes in a package measuring 2.0mm by 1.6mm and supports a wide temperature range from -40 to +105°C. On-chip voltage regulators to filter power-supply noise, enhancing power integrity for module designs. Innovative FlexSwing driver reduces power consumption by 30 percent and integrates source-bias LVPECL resistors.
“Over the past 15 years, SiTime has developed and shipped two generations of MEMS resonators that are used in all our oscillator shipments to date.Our third generation MEMS is now ready and delivers up to seven times better phase noise at half the power,” said Rajesh Vashist, CEO of SiTime, in a statement.
The SiT9501 oscillator is sampling with mass production planned for 1Q21.
