Product details

MEMS XO at 4.0625 MHz with CMOS output

The DSC1033BE1-004.0625T is a MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a fixed 4.0625 MHz CMOS output with ±50 ppm frequency stability. Operating from a 3.3V supply over -20°C to 70°C, it draws 10 mA max in active mode and drops to 1 µA in standby (power-down) — a useful power-save feature for intermittently clocked systems.

Standby function and package outline

Housed in a 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard footprint for board-level clock sources.

Frequently asked questions

Does DSC1033BE1-004.0625T have a standby feature?

Yes, the function is listed as Standby (Power Down). When enabled, the supply current drops to 1 µA max, disabling the output.

Can DSC1033BE1-004.0625T replace a standard quartz oscillator?

As a MEMS-based XO with CMOS output and ±50 ppm stability, it is a drop-in replacement for many quartz oscillators in the same 4-SMD footprint and 3.3V supply rail, provided the frequency and temperature range match.
