The MEMS resonator eliminates the load-capacitance matching and startup margin calculations that quartz crystals require; the oscillator starts reliably without external load caps or a negative-resistance check. ## Blank-programmed — what the BOM engineer needs to plan The DSC8124CI2 ships as a blank (unprogrammed) device — the user must program the target frequency before assembly using Microchip's programming tools or a pre-programming service. This is the same blank-programmable model used across the DSC8124 family; the base product number DSC8124 identifies the family, and the suffix encodes the temperature range and stability grade. For high-volume builds, factor in the programming step or order pre-programmed parts from Microchip's factory-programmed channel.","metaTitle":"Microchip DSC8124CI2 MEMS XO, HCSL, 10-460 MHz, ±25ppm","metaDescription":"Microchip DSC8124CI2 MEMS-based XO (Standard), HCSL output, 10 MHz to 460 MHz, ±25ppm stability, -40°C to 85°C.
