MEMS oscillator at 33.3333 MHz — the quartz alternative that went EOL
The DSC6331MI1HA-033.3333T: Unlike quartz crystal oscillators, the MEMS resonator eliminates quartz supply-chain dependencies and offers better shock and vibration tolerance — but this part is now classified as Obsolete by Microchip.
Supply flexibility and low power for space-constrained boards
The -0.50% down-spread spectrum feature reduces peak EMI emissions — useful for passing radiated emissions testing in systems with high-frequency clocks.
Obsolete — sourcing through independent channels
No pin-compatible direct replacement is documented by the manufacturer.
