Operates from a 1.8V to 3.3V supply rail, covering common logic voltages without needing an external regulator — the same part can be used across 1.8V, 2.5V, or 3.3V domains.
Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard 3.2 x 2.5 mm oscillator footprint that matches many quartz XO layouts for drop-in replacement.
28.6363 MHz.
The evidence does not provide a direct comparison between these two order codes. Both are part of the DSC1001 series and share the same frequency and package, but the suffix difference (CI2 vs AI2) may indicate different temperature grades or stability options — confirm the BOM's required temperature range and stability before substituting.
