Product details

MEMS oscillator for extreme temperature environments

That temperature grade, combined with the MEMS resonator's inherent shock and vibration tolerance, makes this part a fit for avionics, downhole instrumentation, and satellite payloads where a quartz crystal would drift or fail under thermal cycling and mechanical stress.

Supply voltage and power budget

Supply voltage spans 2.25V to 3.6V, covering both 2.5V and 3.3V rails without an external LDO. Maximum supply current is 35 mA when enabled; the disable function (Enable/Disable pin) drops the current to 22 mA max, useful for power-cycling the clock in battery-backed systems.

Package and board layout

Housed in a 6-VDFN exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. The 0.90 mm profile fits under low-clearance enclosures common in portable and rack-mount equipment.

Sourced through independent distribution; quoted to order against the BOM quantity.

Frequently asked questions

What is the operating voltage range of DSC1121AM1-032.7680T?

Designers need to confirm compatibility with 2.25V–3.6V supply before layout.

Where can I buy DSC1121AM1-032.7680T in stock?

Sourcing buyers need immediate availability to avoid production delays.

Is DSC1121AM1-032.7680T obsolete or active?

Brokers and procurement check lifecycle status to avoid last-time buy or redesign costs.

What is the exact replacement for DSC1121AM1-032.7680T?

Maintenance techs need drop-in substitute for failed units without redesign.

How does DSC1121AM1-032.7680T compare to a crystal oscillator?

Engineers evaluating MEMS vs quartz need to understand jitter, stability, and supply benefits.

What is the package code for DSC1121AM1-032.7680T?

Designers must confirm 6-VDFN footprint matches PCB land pattern.
