Product details

MEMS oscillator — no load-cap guesswork

That means you do not need to match a load capacitance or worry about drive level — the silicon resonator is trimmed at the factory and the CMOS output swings rail-to-rail into the clock input of an MCU or FPGA. The 8 MHz fixed frequency with ±25 ppm absolute pull range (APR) holds the clock tight enough for UART baud-rate generation and basic CAN timing without external trimming components.

The 2.25V to 3.6V supply range covers 2.5V and 3.3V rails commonly found on Cortex-M and FPGA boards — no separate regulator needed for the oscillator.

Enable/Disable function and package

The 6-VDFN package (5.00mm x 3.20mm x 0.90mm) is a standard 6-pin footprint — the same land pattern used by many 8 MHz quartz oscillators, so a board layout swap is straightforward.

Frequently asked questions

Can DSC1121BI2-008.0000 replace a standard 8 MHz crystal oscillator?

Yes, if the board uses a standard 8 MHz XO (oscillator module) with CMOS output and Enable/Disable pin. The DSC1121BI2-008.0000 is a MEMS oscillator that drops the need for external load capacitors — it is a drop-in replacement for many 8 MHz quartz XOs in the same 6-VDFN footprint.
