10.4857 MHz MEMS XO with CMOS output – what it is
The DSC1001CI2-010.4857T is a MEMS-based oscillator (XO) from Microchip Technology's DSC1001 series, delivering a fixed 10.4857 MHz CMOS output. It operates from a 1.8V to 3.3V supply rail, drawing a maximum of 6.3 mA – the low current suits always-on or battery-backed clock domains in automotive body controllers or sensor modules.
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 0.126" x 0.098" footprint is common across the DSC1001 family, so a layout change for a different frequency in the same series is a BOM swap, not a board spin.
