Max supply current during active operation is 6.3 mA, so the oscillator's power draw is modest even in always-on applications like a CAN transceiver clock.
Housed in a 4-SMD, no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, this oscillator occupies minimal board area and is compatible with standard reflow soldering profiles.
This part carries an Active product status from Microchip. The Tape & Reel and Cut Tape options mean small quantities are feasible for prototypes as well as production runs.
Yes, this oscillator is rated AEC-Q100, meaning it has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up. It is suitable for automotive electronic control units and other harsh-environment applications.
Frequency stability is ±25 ppm, which covers temperature and voltage variations. This is tight enough for most UART, SPI, and CAN clocking requirements.
The datasheet is available from Microchip's website under the DSC1001 series. It includes full electrical characteristics, timing diagrams, and reflow profile recommendations.
