Product details

Supply flexibility and power budget

Maximum supply current is 35 mA when enabled and 22 mA when disabled via the Enable/Disable function — useful for power-gating the clock in battery-backed or sleep-mode systems.

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 — a standard 7x5 mm footprint that matches many quartz XO footprints, simplifying a drop-in replacement on existing layouts. The Enable/Disable pin lets a system controller gate the output without a separate clock buffer; when disabled, the output goes high-impedance, not a fixed logic level, so downstream clock inputs see a tri-state condition.

It is suitable for both new designs and ongoing production runs. Sourced through independent distribution; current pricing and availability are confirmed at RFQ against your BOM quantity. No stock-holding claim is made — each order is quoted to order.

Frequently asked questions

Is the DSC1121AI2-050.0000 qualified for automotive applications (AEC-Q100)?

Yes, the DSC1121AI2-050.0000 is rated AEC-Q100, which means it has passed automotive-grade reliability stress testing including temperature cycling, ESD, and latch-up.
