The DSC1121AI1-041.5000 is a MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a fixed 41.5 MHz CMOS output. The MEMS resonator eliminates quartz-crystal startup issues and withstands vibration better than a crystal-based oscillator — the base resonator type is the main reliability differentiator here.
Lifecycle status is Active per Microchip's product record.
We source it through independent distribution — submit an RFQ with your target quantity and we will confirm current pricing and lead time against your BOM line.
Within the DSC1121 series, any member with the same 6-VDFN package, CMOS output, and enable/disable function is pin-compatible — the difference is frequency and stability grade. The base product number DSC1121 covers the whole family; confirm the exact frequency and ±50 ppm stability before substituting.
