MEMS oscillator at 50 MHz — what the ratings mean for the BOM
The DSC6101CI2A-050.0000: Unlike a quartz crystal oscillator, the MEMS resonator has no start-up time — the output is valid within microseconds of power-up, which simplifies sequencing in multi-rail designs where the clock must be ready before the core logic exits reset.
AEC-Q100 and the automotive deployment envelope
±25 ppm stability keeps the clock within the tolerance budget for CAN, LIN, and basic Ethernet PHY reference without needing a separate TCXO or oven.
Obsolete — sourcing reality for the BOM line
No pin-compatible direct replacement from Microchip has been published. For a BOM that still carries this line, the procurement path is a per-order quote against the remaining inventory in the channel — no blanket stock commitment exists.
