Product details

The DSC1121CI2-148.5000T is a 148.5 MHz XO (Standard) oscillator from Microchip's DSC1121 series, built on a MEMS resonator with CMOS output. It is AEC-Q100 qualified, making it suitable for automotive electronic systems that require a stable clock source across temperature and vibration. The operating temperature range spans -40°C to 85°C, covering the industrial and automotive cabin-temperature envelope. Frequency stability is ±25 ppm, adequate for most serial communication and processor clocking applications.

Supply voltage range is 2.25V to 3.6V, which covers common 2.5V and 3.3V rails without an external regulator.

The 6-SMD no lead package measures 3.20mm x 2.50mm with a seated height of 0.90mm.

Microchip lists the DSC1121CI2-148.5000T as Active.
