Product details

66.6666 MHz MEMS clock with ±25 ppm hold

This stability figure covers the combined effects of temperature, supply voltage, and aging, so the clock edge at the receiver stays within a 50 ppm window — tight enough for 100BASE-TX Ethernet and most serial data links without external VCXO tuning. Supply voltage spans 1.8V to 3.3V, letting the same oscillator feed a 1.8V FPGA bank or a 3.3V PHY without a level translator.

AEC-Q100 qualification and package footprint

The 4-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight board stacks in engine control units, ADAS modules, or infotainment head units. For a 66.6666 MHz clock driving a gigabit PHY reference, the MEMS construction holds the ppm budget over the product lifetime without recalibration.

Product status is Active.

Frequently asked questions

Is DSC1001CI2-066.6666 RoHS compliant?

RoHS compliance is standard for Microchip's DSC1001 series; confirm the specific date-code compliance at RFQ if your BOM requires a documented RoHS declaration.
