Lifecycle reality for the DSC6101MI2A-006.1679T
The Microchip DSC6101MI2A-006.1679T is listed as Obsolete.
Automotive-grade MEMS timing at 6.1679 MHz
Frequency stability is ±25 ppm — tight enough for CAN, LIN, and most MCU clock trees in automotive body electronics, though a precision GPS or radar reference would typically require ±10 ppm or better. The CMOS output drives standard digital logic loads directly without an external level translator.
4-VFLGA package and board integration
Surface-mount with a 4-pin footprint: the land pattern is standard for this class of MEMS oscillator and matches the Microchip DSC61XX series layout. The small footprint leaves room for decoupling capacitors close to the supply pin, which matters for keeping supply noise from coupling into the output phase noise.
