Product details

The DSC1121AI5-020.0000T: Its CMOS output directly drives the clock input of an MCU, FPGA, or Ethernet PHY without external level translation, and the wide 2.25V to 3.6V supply covers 2.5V and 3.3V logic rails from the same BOM line.

Because the part accepts 2.25V to 3.6V, a single oscillator can serve both the 3.3V I/O bank and the 2.5V core clock on a mixed-voltage board without a separate regulator.

Frequently asked questions

Does the DSC1121AI5-020.0000T have an enable/disable feature?

Yes, the Enable/Disable function allows the output to be gated. When disabled, supply current drops from 35 mA to 22 mA.

Can I replace a quartz oscillator with a MEMS oscillator like the DSC1121?

Yes, in most designs. The DSC1121 uses a MEMS resonator instead of quartz, offering similar frequency stability (±10 ppm) and a wider supply range. Confirm the pinout and output type (CMOS) match your layout.
