MEMS resonator at 50 MHz — 4 mA typ draw
The DSC1033DC1-050.0000T: This is a 50 MHz MEMS-based oscillator, not a quartz crystal — the base resonator is a silicon MEMS structure, which means no crystal aging drift and no start-up time penalty. The typical supply current is 4 mA at 3.3 V, and when the standby pin is asserted the oscillator drops to 1 µA. For a battery-powered design that sleeps most of the time, that standby current is essentially the leakage floor of the PCB.
This oscillator is intended for indoor electronics — office equipment, appliances, consumer PCBs — not for an engine bay, a rooftop telecom enclosure, or a factory floor. If your BOM calls for -40°C operation, this part will not hold ±50 ppm stability at the cold end.
Standby (Power Down) function
The standby function disables the oscillator and puts the output into high-impedance. The disable current is 1 µA maximum. This is a hardware pin — the MCU or system controller pulls it low to shut down the clock tree and save power. No software configuration needed; it is a straight logic-level input.
Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The footprint is a standard 4-pad land pattern — no via-in-pad required, no exposed thermal pad. It reflows on a standard lead-free profile and is supplied on Tape & Reel.
