Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — the 0.50 mm pitch land pattern matches standard oscillator footprints, making it a drop-in replacement for quartz XOs of the same dimensions. No last-time-buy or end-of-life notification has been issued for this order code. As part of the DSC1001 series, the base product number DSC1001 covers multiple frequency and stability variants; the full order code DSC1001CI2-049.0909T specifies the exact frequency and ±25 ppm tolerance.","metaTitle":"DSC1001CI2-049.0909T – Microchip MEMS XO, 49.0909 MHz","metaDescription":"DSC1001CI2-049.0909T: Microchip MEMS XO, 49.0909 MHz, ±25 ppm, AEC-Q100, 1.8-3.3V, CMOS output.
