Product details

MEMS oscillator replaces quartz at 19.2 MHz

The DSC1033DI2-019.2000T is a MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a 19.2 MHz CMOS output from a 3.3V supply.

Standby power-down saves battery life

For a battery-powered sensor that wakes every few seconds to take a reading, the 3 mA typical active current only flows during the measurement window; the rest of the time the oscillator is in standby, extending run time significantly.

Industrial temperature range for outdoor and factory use

That stability holds across the full temperature band, not just at 25°C — important for an outdoor telecom enclosure that sees -30°C overnight or a factory-floor PLC that runs at 70°C ambient. The 4-SMD no-lead package (2.50 mm × 2.00 mm) fits the same footprint as many quartz oscillators, so a board layout designed for a quartz XO can often accept this MEMS part without a respin.

Frequently asked questions

Does DSC1033DI2-019.2000T have a standby power-down function?

Yes. The Standby (Power Down) function disables the output and drops supply current to 1 µA max. Pull the enable pin low to enter standby; pull it high for normal operation.

Is DSC1033DI2-019.2000T replacing a quartz oscillator?

It can serve as a drop-in replacement for a 19.2 MHz quartz XO in the same 4-SMD no-lead footprint, provided the supply voltage is 3.3V and the output is CMOS. The MEMS base resonator eliminates quartz aging and improves shock resistance — a common upgrade path for designs that need better long-term frequency accuracy.
