Overview
The SI501-PROG-DAX is a blank, user-programmable CMEMS oscillator from Silicon Labs. It supports a frequency range of 32 kHz to 100 MHz with LVCMOS output and tri-state enable functionality. The device operates on a supply voltage of 1.71 V to 3.63 V, consuming a maximum current of 6.5 mA. Frequency stability options include ±20 ppm, ±30 ppm, and ±50 ppm, including ten-year aging. It features glitchless start/stop and selectable rise/fall times.
Feature Summary
- Utilizes Silicon Labs CMEMS technology for high stability and low power consumption
- Supports glitchless start and stop operations with selectable rise and fall times
- Offers flexible programming for single-frequency applications with output enable control
Applications
- USB OTG and USB 2.0 interface timing
- Machine-to-machine (M2M) communication modules
- HDMI signal transmission systems
Procurement Notes
This component is supplied as a blank unit requiring end-user programming. Buyers must specify the desired operating frequency during the ordering process via web order notes or direct contact with the manufacturer. Verify that the selected package size matches the target PCB footprint requirements before finalizing procurement.
Selection Notes
Select this model for designs requiring customizable clock frequencies within the 32 kHz to 100 MHz range. Ensure the application environment falls within the specified temperature ranges, such as -40°C to +85°C for industrial use. Confirm that the LVCMOS output voltage levels are compatible with the receiving logic inputs of the target system.
Part Context
The SI501-PROG-DAX belongs to the Si50x family of programmable oscillators, which also includes models like the Si502, Si503, and Si504. While the Si504 offers in-circuit programmability, the SI501-PROG-DAX is designed for pre-programmed deployment after external configuration. This family shares common CMEMS technology and industry-standard footprints.
Replacement Considerations
Direct replacements within the same family include the SI501-PROG-DAXR variant, which differs primarily in packaging format. Other family members like the SI502 or SI503 offer additional frequency outputs but require different programming configurations. Verify pin compatibility and electrical specifications when substituting.
