Product details

64 MHz MEMS XO with ±50 ppm stability

The DSC1033CI1-064.0000T: Operating from a 3.3V supply, the oscillator draws a typical 4 mA during active operation and drops to 1 µA in standby (power-down) mode, making it suitable for duty-cycled or battery-powered systems where the clock tree must be gated off between active periods.

Standby function and power-down control

This lets the system microcontroller gate the clock to save power without a separate enable switch on the supply rail. When the standby pin is de-asserted, the oscillator starts and stabilises within the datasheet's startup time — no external load capacitors or feedback resistors are needed, as the MEMS resonator and PLL are integrated.

Frequently asked questions

What does the standby function do on the DSC1033CI1-064.0000T?

The standby (power-down) function disables the internal oscillator and output buffer, dropping the supply current to 1 µA max. This allows the system to gate the clock off between active periods without a separate supply switch.
