The DSC1502AI3A-125M0000: The ±20 ppm stability means the clock edge stays within 20 parts per million of 125 MHz over temperature and aging — tight enough for most serial data links, Ethernet PHY reference clocks, and FPGA transceiver PLLs that need a clean source without external trimming.
Supply voltage accepts 2.5V to 3.3V, covering both 2.5V FPGA banks and 3.3V logic rails without a separate regulator.
Design engineers need to know if the ±20ppm stability fits their timing budget.
Sourcing buyers need to quickly check distributor inventory to avoid supply delays.
Regulatory compliance is mandatory for many end products.
Buyers need to plan procurement and avoid production stops.
Maintenance technicians often substitute parts and need to verify compatibility.
Design engineers need to ensure the LVCMOS output can drive the load capacitance.
