Product details

The DSC1001CE1-016.5000T is an AEC-Q100 qualified MEMS-based XO (Standard) oscillator from Microchip Technology, delivering a 16.5 MHz CMOS output with ±50 ppm frequency stability across its -20°C to +70°C operating range. Supply voltage spans 1.8V to 3.3V, so it runs from a single 1.8V or 3.3V rail without a secondary regulator. Maximum supply current is 6.3 mA — low enough that the thermal rise inside the 3.2x2.5mm SMD package stays negligible even in a still-air enclosure.

Standby pin and disable current

The disable current is 15 µA maximum — that is three orders of magnitude below the active draw, which matters for battery-backed modules that spend most of their life asleep.

Frequently asked questions

Is the DSC1001CE1-016.5000T compliant with AEC-Q100?

Yes — the DSC1001CE1-016.5000T carries an AEC-Q100 rating, which qualifies it for automotive-grade applications including under-hood and chassis-domain ECUs. The -20°C to +70°C operating temperature range is narrower than the full AEC-Q100 Grade 3 band, so confirm the ambient temperature profile of your target location before committing.

What is the function of the standby pin on the DSC1001CE1?

The standby pin (Power Down function) disables the oscillator output and reduces supply current to 15 µA maximum. It is a logic-level input — driving it low (or high, depending on the configuration variant) stops the clock and cuts power consumption for battery-save or intermittent-duty modes.

How does the DSC1001CE1-016.5000T compare to the DSC1001CE1-016.0000T?

Both are DSC1001 family MEMS XOs with the same package, supply range, and AEC-Q100 rating. The only difference is frequency: 16.5 MHz vs 16.0 MHz. They are not drop-in replacements — the BOM specifies the exact frequency, and a 16.0 MHz part cannot substitute for a 16.5 MHz clock requirement (or vice versa) without changing the system timing.

Is the DSC1001CE1-016.5000T drop-in compatible with standard 3.2x2.5mm oscillators?

Yes — the 4-SMD, No Lead package measures 3.20mm x 2.50mm with a seated height of 0.90mm, matching the industry-standard footprint for 3.2x2.5mm oscillators. The pinout and function (enable/standby) follow the common assignment for this form factor, so it should place onto an existing 3.2x2.5mm land pattern without a board spin.
