Supply voltage spans 2.25 V to 3.6 V, allowing the oscillator to run from a common 2.5 V or 3.3 V rail without an extra LDO. ## 20-VFQFN package – board layout considerations Housed in a 20-VFQFN with exposed pad, 5.00 mm x 3.20 mm footprint and 0.90 mm height. ## Active lifecycle – design-in ready Product status is Active per Microchip's current lifecycle designation. The base product number DSC400 covers the family; this specific variant is the 0202Q0107KI1T frequency and stability option.","metaTitle":"DSC400-0202Q0107KI1T MEMS XO – LVPECL, Dual Freq, Active","metaDescription":"Microchip DSC400-0202Q0107KI1T MEMS XO, LVPECL output, 161.1328125 MHz & 164.375 MHz, ±50 ppm, -40°C to +85°C, 20-VFQFN.
