The ±50 ppm frequency stability holds the clock edge within tight jitter budgets for 10/100BASE-T and CAN-FD timing without external tuning. Operating temperature is -20°C to +70°C, a commercial range that fits interior electronics and infotainment, but not under-hood or outdoor enclosures where -40°C is required. ## Active production — order via RFQ Supply voltage spans 1.8V to 3.3V, covering the three most common digital rails in a single BOM position — no level translation needed when moving between logic families. Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm (0.126\" x 0.098\") with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts in automotive modules and portable equipment.","metaTitle":"DSC1001CE1-066.6666T – Microchip MEMS XO, 66.6666 MHz, CMOS","metaDescription":"Microchip DSC1001CE1-066.6666T MEMS XO: 66.6666 MHz CMOS output, ±50 ppm stability, 1.8V–3.3V supply, AEC-Q100 qualified, active production.
