Microchip lists the DSC1018DI1-028.6363T as obsolete.
A MEMS-based XO (Standard) generating a 28.6363 MHz clock signal in CMOS logic levels. The 1.8V supply rail targets low-voltage cores or I/O banks — confirm the downstream device's VDDIO matches before committing the BOM. Frequency stability is ±50 ppm, adequate for general-purpose timing in MCU or FPGA clock trees.
Industrial temperature range and 4-SMD package
The 4-SMD no-lead package measures 2.50 mm × 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits space-constrained PCB layouts.
