Frequency stability is ±50 ppm, which is sufficient for most CAN, LIN, and general-purpose microcontroller clocking — the 38.4 MHz output is a common multiple for USB and audio sample-rate generation. 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 same footprint as many quartz oscillators, so it drops onto a standard 4-pad land pattern without a board spin.","metaTitle":"DSC1001CE1-038.4000T – Microchip 38.4 MHz MEMS XO, AEC-Q100","metaDescription":"Active production 38.4 MHz MEMS oscillator from Microchip, AEC-Q100 qualified, CMOS output, 1.8-3.3V supply, standby mode.
