Obsolete — sourcing through independent channels
The DSC6122HI2A-00AUT: For a BOM manager or shortage-desk buyer, the key question is date-code consistency and provenance. The laser-etched marking on the 4-VFLGA package should match Microchip's plant code and week format for that production period — a mismatch flags potential re-marked or counterfeit stock.
Dual-frequency MEMS XO — what the ratings mean for fit
The dual-frequency capability means a single oscillator can clock two separate clock domains — for example, a 50 MHz MCU bus and a 100 MHz Ethernet PHY reference — saving a second oscillator footprint. The 3 mA typical supply current keeps the thermal contribution negligible in a dense layout.
The 0.50 mm pitch LGA footprint demands a controlled solder-paste stencil — the land pattern should match the manufacturer's recommended layout to avoid open or bridged joints during reflow. Supplied in tape-and-reel packaging, the part is compatible with standard pick-and-place assembly.
