Programmable Voltage Controlled MEMS Oscillators (VCXO)| SiTIme

SiTime's programmable, MEMS-based Voltage Controlled Oscillators are the most flexible VCXO solutions for telecom, wireless, networking, video, audio, instrumentation and FPGA applications.

Key features:

  • Any combination of frequencies (up to 625 MHz), voltage (1.8V, 2.5V to 3.3V), pull range (±25 PPM to ±1600 PPM) and industry-standard packages (3225, 5032, 7050)
  • LVCMOS outputs (SiT3808, SiT3809, SiT3701) and differential outputs (SiT3821, SiT3822)
  • Best linearity of <1%, 10 times better than quartz VCXO
  • Superior tuning slope (Kv) consistency
  • Widest pull range from ±25 PPM to ±1600 PPM
