Product details

MEMS XO at 2.048 MHz — fit and power budget

The DSC1033CE2-002.0480B is a MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a fixed 2.048 MHz CMOS output at 3.3V with ±25ppm frequency stability. The 4-SMD no-lead package (3.20 x 2.50 mm) fits the same footprint as many quartz oscillators, so a board originally laid out for a crystal oscillator can often take this MEMS part with no layout change.

Active production — no end-of-life watch

Microchip lists the DSC1033CE2-002.0480B as Active.

Frequently asked questions

Where can I buy the DSC1033CE2-002.0480B and how is it quoted?

We source this active Microchip MEMS oscillator through independent distribution. The part is in production, so no last-time-buy constraints apply.

What is the standby current of the DSC1033CE2?

Standby (Power Down) disable current is 1 µA maximum. Active current is 3 mA typical. The standby mode shuts down the output and the internal oscillator while keeping the supply rail connected — useful for battery-powered designs where the clock tree is gated during sleep.

Does the DSC1033CE2-002.0480B support standby mode?

Yes, the function is listed as Standby (Power Down). The enable pin (typically pin 1 on the 4-pin MEMS oscillator footprint) pulls the output to high-impedance and drops supply current to 1 µA max. No external pull-up is needed on the output during standby.
