When disabled, the output enters a high-impedance state, which lets multiple oscillators share a clock line or lets a system controller power down the clock tree without removing the supply rail."},{"question":"What voltage range does the DSC1222DL1-156M2500T support, and is it compatible with 3.3V?","answer":"The supply voltage range is 2.5V to 3.3V, so it works directly on a 3.3V rail without an external regulator. The LVPECL output levels scale with the supply, so the receiver must be rated for the same Vcc."},{"question":"Is there a pin-compatible alternative to the DSC1222DL1-156M2500T in the DSC12X2 family?","answer":"The DSC12X2 series shares the same 6-VDFN footprint and pinout across multiple frequency and stability options. For a different frequency or tighter stability, another member of the DSC12X2 family can be substituted without a board layout change — confirm the output type (LVPECL) and supply voltage match."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1222DL1-156M2500T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1222DL1-156M2500T when reusing this data.
