Why choose a MEMS oscillator over quartz for this BOM line
The DSC1001CC2-025.0000T is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a 25 MHz CMOS output with ±25 ppm frequency stability across its 0°C to 70°C operating range. Unlike quartz crystal oscillators, the MEMS resonator eliminates start-up reliability issues from mechanical shock or vibration — a common failure mode in automotive and portable equipment.
Supply voltage range and power budget
Maximum supply current is 6.3 mA at full output load, which keeps the thermal contribution negligible in a 3.2 mm × 2.5 mm 4-SMD package.
