The wide voltage tolerance also helps when the supply rail droops under load — the oscillator keeps running down to 2.25 V. That covers outdoor base stations, factory-floor controllers, and engine-bay modules where the ambient can hit 85°C and the local self-heating adds another 20°C.
Programming — blank part, user must program
This part ships as a blank device (Programmable Type: Blank (User Must Program)). You program the output frequency using Microchip's TimeFlash field programmer or the factory programming service. The blank part lets you stock one order code and program the exact frequency you need at the time of assembly, rather than ordering pre-programmed parts for each BOM variant.
Housed in a 6-VDFN package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. Frequency stability is ±20 ppm over the operating range — tight enough for most serial communication links (UART, SPI, I2C) and general-purpose clocking. For applications requiring better than ±20 ppm, a different stability grade in the DSC1101 family would be needed.
