Product details

66 MHz MEMS oscillator with CMOS output

The DSC1121CI2-066.0000T: The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal — a meaningful reliability edge in motor-drive or outdoor telecom environments where mechanical stress is a concern.

Supply range and power budget

Maximum supply current is 35 mA when enabled; the disable function drops it to 22 mA max, useful for power-sensitive designs that gate the clock during sleep.

This is a production part suitable for new designs and ongoing BOM positions. Sourced through independent distribution; quoted to order against the BOM quantity.

Frequently asked questions

Is DSC1121CI2-066.0000T RoHS compliant?

The part is supplied in a 6-VDFN package on tape & reel. Microchip's DSC1121 series is generally RoHS-compliant; the specific compliance statement is in the product datasheet. If you need a formal RoHS certificate of compliance for your BOM audit, request it at RFQ time.
