Instant Oscillators

Field programmable oscillators can be programmed by the Time Machine II to support a wide range of oscillator configurations:

  • Any frequency
  • Any voltage
  • Any stability
  • Any package


Don't waste time searching and waiting for oscillators. Program SiTime MEMS field programmable devices to your exact specification and create drop in replacements for legacy quartz oscillators within seconds.

SiTime offers field programmable devices for MEMS XO, MEMS VCXO and MEMS spread spectrum XO families. These devices are available in single-ended (LVCMOS) and differential (LVPECL and LVDS) signaling types.

Note:

  • Field programmable devices for a given oscillator family can be configured to support a wide range of specifications available within that product family. For example, the SiT8008AI-11-XXX-000.FP000 allows a user to program any frequency between 1 to 110 MHz with any stability of ±20, ±25 or ±50 PPM over industrial or extended commercial temperature ranges and with any voltage supply of 1.8V, 2.5V, 2.8V or 3.3V, in a 2.5 x 2.0 (mm x mm) standard 4-pin oscillator package. As such, it can be programmed to match specifications of both the SiT8008 and the SiT1602 families.
  • The field programmable devices are currently offered in T&R only.
