The DSC1121CE2-100.0000T is a 100 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1121 series, delivering a CMOS output with ±25 ppm frequency stability across its -20°C to 70°C operating range. AEC-Q100 qualification qualifies this part for automotive applications where temperature cycling and vibration resistance are required, such as infotainment head units, camera modules, or ADAS sensor timing.
Maximum supply current is 35 mA when enabled and 22 mA when disabled, so the power budget for a 3.3 V rail is roughly 116 mW active and 73 mW in disable mode.
Package and footprint for 6-SMD layout
Housed in a 6-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the footprint is compatible with standard 3.2 x 2.5 mm oscillator land patterns. Surface-mount assembly on a 6-pad layout; the no-lead construction reduces parasitic inductance compared to a leaded package, which matters for 100 MHz edge rates.
