Automotive-grade MEMS oscillator with wide frequency range
The DSC1201NA3-PROG is a MEMS-based XO (Standard) from Microchip's DSC12X1 series, delivering a CMOS output across a programmable frequency range of 2.5 MHz to 170 MHz. The blank (user-programmable) type means the oscillator ships without a frequency set — you program it to your exact frequency using Microchip's programming tools. This gives design flexibility but adds a programming step before assembly, so factor that into your production flow.
The wide supply range of 2.25V to 3.63V covers 2.5V and 3.3V logic rails without an extra regulator — useful when the same BOM serves multiple board variants. Maximum supply current is 27 mA typical, which is modest for a high-frequency MEMS oscillator and keeps the thermal impact on the 6-VDFN package low.
Housed in a 6-VDFN package measuring 7.00mm x 5.00mm with a seated height of 0.90mm, this oscillator suits space-constrained automotive and industrial PCBs. The surface-mount footprint is straightforward for a 4-layer board; the low profile helps when clearance to an enclosure lid is tight.
