That frequency is common in Ethernet PHY reference clocks and video pixel timing; the ±50 ppm stability keeps the link within the 100 ppm total budget for 100BASE-TX without a separate TCXO. Supply voltage spans 1.71 V to 3.63 V, so the same part serves 1.8 V, 2.5 V, or 3.3 V logic domains — no level shifter needed on the clock line. ## Obsolete status – sourcing reality for the BOM line Microchip lists the DSC6003CE1A-044.2368 as Obsolete. If you need a pin-compatible replacement within the same DSC60XX family, the evidence does not name a specific alternative. A functional equivalent with the same 44.2368 MHz frequency, CMOS output, and AEC-Q100 grade would require a different order code — the BOM position may need a layout review if the package footprint differs. ## Package and mounting – 4-SMD no-lead footprint The 4-SMD, No Lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm.","metaTitle":"DSC6003CE1A-044.2368 Microchip MEMS XO – Obsolete, AEC-Q100","metaDescription":"DSC6003CE1A-044.2368 Microchip MEMS XO, 44.2368 MHz CMOS, AEC-Q100, ±50 ppm, 1.71–3.63 V.
