Obsolete — sourcing through independent channels
The DSC6122CI2A-00AY: For BOM lines that still require this exact order code, independent surplus and broker channels remain the supply path.
Dual-frequency MEMS XO in a 4-VDFN package
The dual-output capability saves a second oscillator footprint on dense timing boards. For a 26 MHz carrier, that translates to a worst-case drift of ±650 Hz — tight enough for most MCU clock trees and USB full-speed references. Maximum current draw is 3 mA typical, making it suitable for battery-operated or power-constrained designs. The land pattern matches the standard 4-pin oscillator footprint — no board redesign needed if migrating from a quartz XO in the same outline.
