Lifecycle reality for a BOM line
The DSC6121HI2A-00AKT: For a BOM that already carries this order code, the immediate decision is whether the existing allocation covers remaining build requirements or whether a replacement oscillator needs qualifying.
What the dual-output MEMS oscillator delivers
A single oscillator covering two common clock rates saves board space and reduces BOM count in applications like Ethernet PHYs (25 MHz) and HDMI/USB controllers (27 MHz), where both frequencies are needed on the same PCB.
Maximum current draw is 3 mA typical — low enough for battery-powered or thermally constrained enclosures where every milliwatt counts.
Sourcing an obsolete MEMS oscillator
No blanket stock claim; each lot is verified for authenticity and condition before it ships.
