Product details

MEMS resonator vs quartz — what the 25.0012 MHz buys

Supply range and stability — timing margin across conditions

With a 2.25V to 3.6V supply range, this oscillator can run off a 2.5V or 3.3V rail without a separate regulator — useful when the FPGA bank voltage is already present and you do not want an extra LDO just for the clock.

Package and mounting — 6-SMD footprint

The 6-SMD, No Lead package measures 3.20mm x 2.50mm with a seated height of 0.90mm — a compact footprint that fits dense PCB layouts, but the 0.126" x 0.098" land pattern requires a well-controlled solder-paste stencil to avoid bridging on the no-lead pads.

Frequently asked questions

What is the closest pin-compatible alternative in the DSC1121 series?

The DSC1121 family shares the same 6-SMD, No Lead package and pinout across all frequency variants. A different frequency (e.g., DSC1121CE1-025.0000) is a direct drop-in replacement for the same 25.0012 MHz socket only if the system clock tolerance allows the frequency difference — confirm the PLL reference or baud-rate generator requirements before swapping.
