Product details

The DSC1001CI1-019.2000T is a 19.2 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output in a 3.20 mm x 2.50 mm 4-SMD no-lead package.

A standby (power-down) function drops the supply current to 15 µA max when disabled, compared to 6.3 mA max during active operation — useful for ignition-off domains or battery-backed modules that must preserve quiescent draw. The supply voltage range of 1.8 V to 3.3 V lets the oscillator run from the same rail as the downstream MCU or transceiver without an extra regulator.

Frequently asked questions

Is DSC1001CI1-019.2000T AEC-Q100 qualified?

Yes, the DSC1001CI1-019.2000T carries AEC-Q100 ratings, meaning it has passed the automotive-grade qualification tests for temperature, reliability, and ESD. This is a prerequisite for PPAP submission in automotive applications.

Does DSC1001CI1-019.2000T have a standby power-down function?

Yes, the standby (power-down) function disables the output and reduces supply current to 15 µA max, versus 6.3 mA max during active operation. The output is tri-stated when disabled.

How does DSC1001CI1-019.2000T compare to a standard quartz oscillator?

The DSC1001 uses a MEMS resonator instead of a quartz crystal. MEMS oscillators typically offer better shock and vibration tolerance, faster start-up, and smaller footprint at equivalent frequency stability (±50 ppm). The AEC-Q100 qualification is an additional reliability layer not always available on standard quartz XOs.
