Maximum active supply current is 8.7 mA — a light load for a 70 MHz clock, leaving headroom for multiple fan-outs on a single output without exceeding the oscillator's drive capability. Housed in a 4-SMD no-lead package measuring 3.20 mm × 2.50 mm with a seated height of 0.90 mm, it fits the same footprint as standard quartz oscillators — a direct drop-in for existing 3.2×2.5 mm XO pads.","metaTitle":"DSC1001CI5-070.4550T MEMS XO – 70.455 MHz, ±10 ppm, AEC-Q100","metaDescription":"Microchip DSC1001CI5-070.4550T: MEMS XO, 70.455 MHz CMOS output, ±10 ppm stability, AEC-Q100, -40°C~85°C, 1.8V–3.3V supply.
