Product details

MEMS oscillator for 80 MHz clock trees

The DSC1121BI2-080.0000 is a MEMS-based standard oscillator (XO) that replaces quartz crystal oscillators in 80 MHz clock applications. Its CMOS output interfaces directly with MCU, FPGA, and SoC clock inputs without level translation. Frequency stability of ±25 ppm keeps the clock edge within tight timing margins for USB, Ethernet, and serial interfaces over temperature.

Housed in a 6-SMD no-lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts without requiring via-in-pad.

Frequently asked questions

Where can I buy DSC1121BI2-080.0000 and what is the lead time?

This part is Active and available through independent distribution. We source it per RFQ — submit your BOM quantity for a current price and lead-time confirmation. No stock-holding claim; availability confirmed at quote time.

Does DSC1121BI2-080.0000 work with a 3.3V supply?

The CMOS output swings rail-to-rail, compatible with 3.3 V logic inputs.

Is DSC1121BI2-080.0000 equivalent to a standard quartz oscillator?

Functionally yes — it is a standard XO (oscillator) that outputs a CMOS clock at 80 MHz. The difference is the MEMS resonator inside instead of a quartz crystal. MEMS oscillators typically offer better shock and vibration resistance and faster startup than quartz, but the electrical interface is the same.
