MEMS oscillator for flexible clock generation
The DSC8101BI5: This means the clock edge stays within tight bounds across thermal cycling, which matters for serial interfaces (UART, SPI, I²C) where bit timing accumulates over long frames.
Blank-programmable — one part number, many frequencies
The DSC8101BI5 ships as a blank device (Blank (User Must Program)), meaning the target output frequency is programmed by the user — typically at board programming or via a one-time factory-programming step. For a design that needs multiple clock frequencies across variants (e.g. 25 MHz for Ethernet, 50 MHz for MCU core, 125 MHz for SDRAM), a single DSC8101BI5 order code covers the whole range, reducing the number of unique line items on the BOM.
6-SMD No Lead — board-fit footprint
The tube packaging is typical for manual placement or low-volume reflow; for high-volume tape-and-reel, confirm the reel option with the distributor at RFQ.
