Product details

MEMS XO for extreme-temperature clock trees

The DSC1101CM1-033.3333 is a MEMS-based oscillator (XO) delivering a fixed 33.3333 MHz CMOS output — a standard reference for Ethernet PHYs, SoC clock trees, and FPGA configuration clocks.

Supply tolerance and power-down budgeting

That 95 µA standby draw matters for battery-backed systems where the oscillator must be disabled during sleep but wake on a threshold event.

The 6-SMD, no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm, a common footprint that mates with standard reflow profiles.

Frequently asked questions

Does the DSC1101CM1-033.3333 have a power-down feature?

Yes — the function is listed as Standby (Power Down). When enabled, the maximum disable current is 95 µA, compared to 35 mA during active operation.

What is the frequency stability of the DSC1101CM1-033.3333?

The frequency stability is ±50 ppm over the full operating temperature range and aging. This is typical for a MEMS XO and adequate for most serial interface reference clocks.
