Product details

The ±10 ppm frequency stability means the clock edge jitter stays within the timing budget for a 100BASE-TX transceiver or a Cortex-M4 PLL without external re-tuning.

Automotive-grade temperature coverage

The AEC-Q100 designation means it passed the reliability stress tests (preconditioning, temperature cycling, biased HAST) that commercial-grade parts skip.

Wide supply voltage simplifies BOM

Accepts 1.8V to 3.3V supply without a separate regulator — a single oscillator covers both a 1.8V FPGA bank and a 3.3V MCU I/O domain, reducing the BOM line count.

Frequently asked questions

Is DSC1001CI5-037.0879T compatible with 1.8V and 3.3V supplies?

Yes — the supply voltage range is 1.8V to 3.3V, so it works on both rails without a separate regulator. The CMOS output swings rail-to-rail, so the logic levels match the supply voltage of the receiving device.
