Product details

Dual-frequency MEMS oscillator for tight timing budgets

The DSC6122CI2A-00AYT: With CMOS output, it directly drives standard digital logic without external level translation — useful for dual-clock systems where a single oscillator replaces two cans.

Obsolete — sourcing through independent channels

Stock is available through independent surplus and broker channels. Each reel is lot-traceable and verified against the original Microchip datasheet before shipment.

Package and board-fit specifics

The 4-VDFN package (3.2 mm x 2.5 mm, 0.90 mm height) is a standard land-grid array with four peripheral pads — the same footprint as many 4-pin MEMS oscillators, so it retrofits existing layouts without a board spin. The 0.90 mm seated height suits tight mezzanine or card-edge clearances.

Frequently asked questions

What is the closest pin-compatible alternative to DSC6122CI2A-00AYT?

No official pin-compatible replacement is listed by Microchip. The DSC61XX family includes other dual-output MEMS XOs with the same 4-VDFN footprint, but each has a different frequency set — check the family selector for a match on 26/27 MHz.
