Supply voltage spans 2.25V to 3.6V — one oscillator covers both 2.5V and 3.3V logic rails without a separate LDO.
Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm — the footprint matches the industry-standard 7x5 mm oscillator land pattern.
Sourcing buyers need immediate availability and pricing from authorized distributors to avoid production delays.
Design engineers must ensure the oscillator operates within the system's power supply rails.
Maintenance techs and design engineers need to know compatibility without redesigning the PCB.
Power-sensitive designs require controllable output to reduce consumption in idle states.
PCB layout engineers need exact dimensions for footprint creation and clearance checks.
Compliance with environmental regulations is mandatory for many end-products and supply chain audits.
