Product details

Obsolete — sourcing reality for the BOM line

The DSC6121CI2A-00ETT: No official successor order code is recorded, so a direct drop-in replacement from the same manufacturer is not available. For new designs, a pin-compatible MEMS oscillator from the same family with the same footprint and supply range should be evaluated as a functional alternative.

Frequently asked questions

What is the DSC6121CI2A-00ETT used for?

It is a dual-output MEMS oscillator that provides a 75 MHz and a 100 MHz CMOS clock from a single 4-VDFN package. Typical applications include clocking FPGAs, Ethernet PHYs, microcontrollers, or any digital logic that needs two independent reference frequencies in a compact, low-power footprint.
