The DSC1525MI2A-33M33333T is a MEMS-based XO (Standard) from Microchip's DSC152X series, delivering a 33.33333 MHz LVCMOS clock output from a 1.8V supply rail. The 4-VFLGA package (2.00mm x 1.60mm) is a small footprint — plan for a 0.50mm pitch fan-out on a 2-layer board; the enable/disable function lets you gate the clock for power savings in battery-backed designs.
The 1.8V supply is the core voltage for many low-power MCUs and FPGAs — this oscillator runs directly off that rail without a separate LDO. The ±25ppm frequency stability covers the full temperature range and supply variation, so a 33.33333 MHz clock stays within 833 Hz of nominal across -40°C to 85°C — tight enough for a UART baud-rate generator or a USB full-speed reference. Max supply current is 7.5 mA — the MEMS core draws less than a quartz oscillator with its output buffer, which matters when you're tallying the power budget on a sensor node or a portable instrument.
