Product details

156.25 MHz MEMS oscillator for Ethernet and FPGA reference clocks

Supply voltage spans 2.25V to 3.63V, so the same part runs from a 2.5V or 3.3V rail without an external LDO — one BOM line covers both power domains.

Active production — no last-time-buy risk

Enable/disable function and disable current

6-SMD no-lead package — board layout fit

Housed in a 6-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The no-lead footprint means the pads are flush with the package body — reflow profile follows the standard JEDEC J-STD-020 for MSL, and the small outline fits dense PCB layouts where height is constrained.

Frequently asked questions

What is the current lifecycle status of DSC1121BI2-156.2500? Is it active or obsolete?

Buyers need assurance the part is still in production and will be available for future orders.

Where can I buy DSC1121BI2-156.2500 in stock today?

Quick availability is critical to avoid production delays and expedite time-to-market.

What is the price of DSC1121BI2-156.2500 for a reel of 1000?

Volume pricing directly impacts BOM cost and procurement decisions for high-volume builds.

Is DSC1121BI2-156.2500 a direct replacement for a 156.25 MHz quartz oscillator?

Engineers need to know if they can swap without redesigning the PCB or changing external components.

What is the output drive strength of DSC1121BI2-156.2500?

Output drive affects signal integrity and compatibility with downstream logic families.

Does DSC1121BI2-156.2500 support enable/disable and what is the disable current?

Enable/disable functionality is used for power saving; knowing standby current is essential for low-power designs.
