MEMS dual-output oscillator — 4-VDFN footprint
The DSC6121CI2A-00EWT: The 4-VDFN package footprint demands a standard reflow profile — the 0.89 mm height fits under low-profile shielding cans common in compact wireless modules and IoT edge nodes.
Obsolete — sourcing through independent channels
A board-spin to a current-production MEMS oscillator from the same DSC61XX family is the recommended long-term migration path, though the replacement will require validating the footprint, output frequency plan, and supply voltage against the original design.
