What this MEMS XO delivered in its production run
The 1.71V–3.63V supply range allowed it to run from a 1.8V or 3.3V rail without a separate regulator.
Sourcing the DSC6001HI2A-038.0000 today
As an obsolete line, the DSC6001HI2A-038.0000 is available only through independent surplus channels. The 4-SMD, no-lead package (1.60mm x 1.20mm) is a common footprint for MEMS oscillators, but the exact frequency and AEC-Q100 grade narrow the replacement pool. A pin-compatible functional equivalent from the same DSC60XX family would require matching the 38 MHz frequency, CMOS output, and ±25 ppm stability.
