Housed in a 4-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm — this is the standard 5.0 x 3.2 mm oscillator footprint, compatible with industry-standard land patterns and reflow profiles. Surface-mount mounting on a standard PCB; the no-lead package keeps the parasitic inductance low at 22.579 MHz, so the CMOS output edge rate is clean without series termination resistors in most layouts.","metaTitle":"DSC1001BI2-022.5790T Microchip MEMS XO 22.579 MHz CMOS","metaDescription":"Microchip DSC1001BI2-022.5790T MEMS oscillator: 22.579 MHz, CMOS output, ±25 ppm stability, AEC-Q100, -40°C to 85°C.
