Frequency stability and package footprint
The DSC8001CI1: Total frequency stability is ±50 ppm, adequate for UART, SPI, I2C, and general-purpose clocking; tighter stability applications (e.g., Ethernet) may require a TCXO.
Programmable frequency — blank device
This order code is a blank (unprogrammed) unit — the user must program the desired output frequency via Microchip's factory programming service or a compatible programmer. Because it is not a fixed-frequency part, the same DSC8001CI1 BOM line can serve multiple frequency requirements by programming each device, reducing inventory line items.
