The MEMS resonator inherently withstands shock and vibration better than quartz-based oscillators, and the device starts up in under 5 ms typical. ## Supply voltage and frequency stability The wide input range simplifies power tree design in mixed-voltage systems. Maximum supply current is 42 mA at full frequency; disabling the output (Enable/Disable pin) drops consumption to 22 mA max. For applications requiring better than ±25 ppm (e.g., SyncE or IEEE 1588), a TCXO or OCXO would be needed. ## Programming and packaging The DSC8124AI2 ships as a blank (unprogrammed) device — the user must program the target frequency using Microchip's TimeFlash or a compatible programmer before assembly. This allows a single stock-keeping unit to cover multiple frequency requirements, reducing inventory complexity. Supplied in tube packaging.","metaTitle":"Microchip DSC8124AI2 MEMS XO, HCSL, 10-460 MHz, AEC-Q100","metaDescription":"DSC8124AI2 MEMS-based XO (Standard) from Microchip Technology.
