Product details

MEMS oscillator at 40 MHz with automotive-grade qualification

The DSC1001BI1-040.0000T is a 40 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output across a 1.8V to 3.3V supply range.

Package, footprint, and supply current

Housed in a 4-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm — a standard 5x3.2 mm footprint that matches many quartz XO footprints, so the board layout can often stay the same when swapping from a crystal to this MEMS part. Maximum supply current is 7.2 mA at 40 MHz, and the disable current sits at 15 µA — the active draw is low enough for a 3.3V rail shared with an MCU without a dedicated LDO.

Frequently asked questions

Is DSC1001BI1-040.0000T active or obsolete?

Buyers need to know if the part is available for new designs or if they should look for a replacement.

What are the supply voltage and output type of DSC1001BI1-040.0000T?

Design engineers must confirm compatibility with their circuit voltage rail and logic family.

What is the footprint and package of DSC1001BI1-040.0000T?

Mechanical fit is critical for PCB layout, especially given the 5.0x3.2mm 4-SMD package.

Does DSC1001BI1-040.0000T have a standby or power-down feature?

Power-sensitive designs require the standby function for low-power modes.

Where can I buy DSC1001BI1-040.0000T and what is the lead time?

Sourcing buyers and brokers need to find stock quickly to avoid production delays.

What are equivalent or alternative parts to DSC1001BI1-040.0000T?

Engineers and procurement need cross-reference options for second sourcing or if the part is hard to get.
