Operating from a 3.3V supply, it draws a maximum of 4 mA typical — low enough for battery-powered or thermally constrained designs where every milliwatt counts.
Housed in a 4-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm, this oscillator fits standard 5x3.2mm clock footprints — verify the pad layout against your BOM's existing crystal or oscillator land pattern.
This is a MEMS-based XO, not a bare crystal — it generates a full CMOS clock output at 50 MHz with ±25ppm stability. It replaces a quartz oscillator of the same frequency, output type, package footprint (5.0x3.2mm, 4-pin), and supply voltage (3.3V). Confirm the standby function pinout matches your design; the DSC1033 series includes a power-down pin that may differ from a simple enable.
