If the board sees outdoor or engine-bay ambient, step up to the industrial-grade DSC1122 variant. Housed in a 6-SMD no-lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm. The 0.197\" × 0.126\" footprint matches the standard 5×3.2 mm oscillator land pattern — no layout surprises if you are replacing a quartz XO in the same size.

For a 125 MHz clock, LVPECL provides a differential signal with better noise immunity and lower jitter over long PCB traces or cables — choose the DSC1122 when driving a high-speed ADC, FPGA, or SerDes reference."},{"question":"Is the DSC1122BE1-125.0000 compatible with 3.3V logic?","answer":"Yes. The supply voltage range of 2.25V to 3.6V covers 3.3V rails directly. The LVPECL output swing is typically 800 mV peak-to-peak centered around Vcc – 1.3V, so it AC-couples into 3.3V CML or LVPECL receivers with the correct termination."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1122BE1-125.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122BE1-125.0000 when reusing this data.
