The -55°C to 125°C range covers Grade 1 ambient — an ECU sitting near the engine block on a 105°C summer day still has 20°C of margin before the oscillator hits its upper limit.
The 2.25V to 3.6V supply range means this oscillator runs directly from a 3.3V or 2.5V rail — no separate LDO needed.
Design engineers need full specifications to validate fit and performance.
Sourcing buyers need pricing and distributor availability for BOM costing.
Automotive applications require AEC-Q100 certification for reliability.
Engineers may need cross-reference for alternative sourcing or design flexibility.
Output compatibility with downstream logic is critical for design integration.
Prototyping and small-run production require low minimum order quantities.
