Product details

The DSC1121AE5-010.0000 delivers a 10 MHz reference clock from a MEMS resonator, with ±10 ppm frequency stability across its -20°C to 70°C operating range — tighter than the ±25 ppm typical of many quartz oscillators, which means fewer timing errors in UART baud-rate generation or USB frame synchronization.

Supply range and output control

The supply voltage spans 2.25V to 3.6V, covering both 2.5V and 3.3V logic rails without a separate regulator — a single BOM line serves designs that run mixed-voltage domains.

Housed in a 6-SMD No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — the same footprint used by many quartz oscillators, so the PCB layout can accept either technology without a board spin.

Frequently asked questions

Where can I buy DSC1121AE5-010.0000?

Buyers need to find authorized distributors and compare price/stock for procurement.

What is the pinout and package size of DSC1121AE5-010.0000?

Design engineers must verify PCB footprint and connectivity before layout.

Is DSC1121AE5-010.0000 a direct replacement for a 10MHz quartz oscillator?

Buyers evaluating MEMS vs quartz need to know compatibility and performance differences.

What is the supply voltage range for DSC1121AE5-010.0000?

Confirming voltage compatibility prevents circuit damage or failure.

How to enable or disable the output on DSC1121AE5-010.0000?

Functionality needed for power management or test modes; missing this can cause system glitches.

What is the lead time for DSC1121AE5-010.0000 from major distributors?

Sourcing buyers need to plan BOM fulfillment and avoid production delays.
