It ships with two independent output frequencies, each programmable from a list that includes 100 MHz, 125 MHz, 156.25 MHz, 312.5 MHz, and up to 450.68 MHz. That means one part can clock both a SerDes reference and a logic core, saving a second oscillator slot.
Housed in a 14-VFQFN exposed-pad package measuring 3.20 mm x 2.50 mm with a 0.90 mm height. Microchip lists the DSC2033FI2-F0038 as Active.
Within the DSC2033 series, other order codes differ by frequency stability grade (±25 ppm vs ±50 ppm) or output frequency pair. The pinout and package are identical across the family, so swapping to a different stability or frequency variant requires no board change — just update the BOM line.
