Its 1.71V–3.63V supply rail covers both 1.8V and 3.3V logic domains, so a single part number can serve multiple clock trees on the same board. The 4-SMD No Lead package (3.20mm x 2.50mm x 0.90mm) is a standard footprint shared across many MEMS oscillators, so layout reuse is straightforward.
Sourcing reality: obsolete status and what it means
For a pin-compatible replacement, the buyer should evaluate other DSC60XX family members with the same package and supply range — but each frequency variant carries its own order code and lifecycle status.
The total frequency stability of ±50 ppm includes the combined effects of temperature, supply variation, and aging. For a CAN bus or USB clock, this keeps the timing error within the receiver's jitter budget without external trimming.
