Product details

MEMS oscillator for tight-timing, low-power designs

Unlike a quartz crystal that needs external load capacitors and an inverter, this XO (Standard) integrates the resonator and oscillator in one 4-SMD package — a drop-in clock source for MCUs, FPGAs, and communication controllers.

The standby (power-down) function on this oscillator disables the output and reduces current draw to 1 µA max, letting the system clock gate without an external load-switch or GPIO-controlled enable. For a sensor node that wakes every 10 seconds to take a reading, the 3 mA active current runs for milliseconds while the 1 µA standby dominates the rest of the duty cycle — the average current stays well below 100 µA.

Package and footprint for hand-solder and reflow

Housed in a 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard footprint that matches many quartz oscillator packages, so a board layout designed for a 5x3.2 mm can accepts this MEMS part without a spin. No hidden leads under the body.

Frequently asked questions

Can DSC1033BI2-012.0000T replace a standard 12 MHz quartz crystal on my board?

Yes, if your circuit expects a CMOS-level clock input (not a crystal load). The DSC1033BI2-012.0000T outputs a rail-to-rail CMOS clock at 12 MHz, so it replaces a crystal + oscillator circuit or an external clock module in the same 5.0 mm x 3.2 mm footprint. No external load capacitors are needed — the MEMS resonator and drive circuit are inside the package.

Does the DSC1033BI2-012.0000T have a standby or power-down function?

Yes, the part includes a standby (power-down) function. When the enable pin is driven low, the oscillator stops and the supply current drops to 1 µA max. The output goes into high-impedance state, allowing other clock sources to drive the line without contention.
