Product details

The DSC1001AI2-050.0000 is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a fixed 50 MHz CMOS output. Its AEC-Q100 rating qualifies it for automotive-grade reliability, spanning -40°C to +85°C — suitable for under-hood and cabin electronics where vibration and temperature swings are the norm. The 7.2 mA max active current and 15 µA standby current keep the power budget lean for always-on modules.

The 1.8V to 3.3V supply range covers common logic rails without a level translator, simplifying the power tree.

Frequently asked questions

What is the frequency stability of DSC1001AI2-050.0000?

Frequency stability is ±25 ppm. This is tight enough for most serial interfaces (UART, SPI, I2C) and Ethernet clocking without external trimming.

Can DSC1001AI2-050.0000 be used in automotive applications?

Yes, it carries AEC-Q100 qualification, which means it has passed automotive-grade stress tests (temperature cycling, ESD, latch-up).

How does the standby function work on DSC1001AI2-050.0000?

When the standby pin is asserted, the oscillator stops and the output enters high-impedance. Supply current drops to 15 µA max. Releasing standby restarts the output within the start-up time specified in the datasheet.
