What this MEMS XO brings to the board
The DSC6001JE2B-025.0000T is a MEMS-based oscillator (XO) delivering a 25 MHz CMOS clock output with ±25 ppm frequency stability across its -20°C to 70°C operating range. Its 1.71V to 3.63V supply range lets it drop into 1.8V, 2.5V, or 3.3V domains without a separate regulator — useful for multi-rail designs. Typical current draw of 1.3 mA makes it a fit for battery-powered or thermally constrained boards where every milliwatt counts.
Automotive-grade timing for non-automotive temp range
Housed in a 4-VLGA package measuring 2.50 mm x 2.00 mm with a seated height of 0.89 mm, this is a small, low-profile part — the MEMS die sits in a ceramic land-grid array with no leads to inspect. Reworking a VLGA under hot air is doable but fussy: the package has no visible pin 1 mark beyond the datasheet corner index, and the tiny pads demand a fine tip and steady hand to avoid bridging or tombstoning. Pre-bake at 125°C for 8 hours if the parts have been exposed to ambient humidity — the MSL level is not listed, but MEMS resonators can absorb moisture and shift frequency if not dried before reflow.
