SiTime has a wide range of MEMS-based differential oscillators that support LVPECL, LVDS, and HCSL formats. The SiT936x Elite Platform oscillators have the best jitter performance at 230 fs (femtoseconds) rms typical over an integration range of 12 kHz to 20 MHz, while the SiT912x family has good jitter at 0.5 ps (picoseconds) rms, but with lower power and with a 1.8-V VDD option. These MEMS oscillators have several internal architectural advantages that make them superior to their quartz differential oscillator counterparts.
