Si50x CMEMS Programmable Oscillators

Silicon Labs' Si50x CMEMS® programmable oscillators and field programmer board

Image of Silicon Laboratories' Si50x CMEMS® Programmable OscillatorsSilicon Labs’ CMEMS field programmer kit creates custom samples instantly with any supported frequency or product configuration. The kit provides an instant orderable part number and data sheet addendum with the OPN, device configuration, date created, and user name for easy record keeping. The kit is compatible with most future Silicon Labs CMEMS devices.

The field programming kit includes:

  • Si501-2-3-4 field programmer board
  • USB Type B retractable cable
  • 5 pieces Si501-PROG-BAX - 3.2 x 4 mm blank parts
  • 5 pieces Si501-PROG-CAX - 2.5 x 3.2 mm blank parts
  • 5 pieces Si501-PROG-DAX - 2 x 2.5 mm blank parts
  • Each kit requires an up-to-date version of the Windows-based software to program the CMEMS devices.

Si50x CMEMS® Oscillators

Silicon Labs’ Si50x CMEMS® oscillator family provides highly reliable MEMS oscillators to replace standard crystal oscillators (XO). The CMEMS benefits include 10-year guaranteed frequency stability at ±20ppm including shock, vibration, voltage and aging, at constant operation across the industrial temperature range of -40°C to 85°C. Other less stringent performance levels are also available. The configurable device supports any frequency between 32 kHz and 100 MHz, configurable output rise and fall times, and configurable OE functionality for ultra-low-power sleep states. The family is drop-in compatible to general purpose XO sockets in 4-pin 3.2 x 5 mm, 2.5 x 3.2 mm, and 2 x 2.5 mm packages.
