The DSC1203CI3-106M2500 is a MEMS-based standard XO delivering a 106.25 MHz LVDS output — a common reference frequency for 10GbE SerDes, FPGA transceivers, and PCIe Gen 3 clocking. The MEMS resonator eliminates quartz startup jitter and vibration sensitivity, making it a fit for industrial and outdoor equipment where crystal oscillators drift under mechanical shock.
The supply voltage accepts 2.5V to 3.3V, so the same part can be used on a 2.5V FPGA bank or a 3.3V ASIC rail without a separate regulator. Typical active supply current is 32 mA at 106.25 MHz LVDS — the LVDS output stage draws more than a single-ended CMOS oscillator, but the differential signal rejects common-mode noise over long PCB traces or cables.
No pin-compatible second source is documented, but the DSC1203 series shares the same 6-VDFN footprint across frequency variants — a BOM change to a different DSC1203 frequency requires only a new order code, not a board spin.
Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. Surface-mount reflow follows standard lead-free profiles — no special bake or dry-pack handling beyond MSL level 1 (moisture sensitivity not specified, but typical MEMS oscillators are MSL 1).
