Operating from a 2.25V to 3.6V supply, this oscillator can be powered directly from a 2.5V or 3.3V rail—no intermediate LDO needed, which simplifies the power tree and saves board area. Housed in a 20-VFQFN exposed pad package measuring 5.00 mm x 3.20 mm with a 0.90 mm height, the DSC400-0202Q0109KI1 requires a thermal pad on the PCB for heat dissipation; the exposed pad must be soldered to a ground plane to meet the datasheet thermal resistance.","metaTitle":"DSC400-0202Q0109KI1 MEMS XO, LVPECL, 153.6/176.875 MHz","metaDescription":"Microchip DSC400-0202Q0109KI1 MEMS XO, LVPECL output, dual frequency 153.6/176.875 MHz, ±50 ppm stability, -40°C to +85°C, 20-VFQFN.
