Operating from 1.8V to 3.3V, this oscillator can be powered from a 1.8V core rail or a 3.3V I/O rail without a separate regulator — a single BOM entry serves multiple voltage domains in mixed-voltage designs. Active current draw is 7.2 mA max at 50 MHz, which is typical for a MEMS oscillator at this frequency and keeps the thermal budget low in the 4-SMD, No Lead package (3.20 mm x 2.50 mm).
No official successor or second-source is recorded, but the DSC1001 family includes multiple frequency and stability options for cross-reference.
