It requires a 50-ohm termination to Vcc-2V at the receiver, not a simple pull-up. The 312.5 MHz frequency is well within LVPECL's bandwidth, and the differential swing gives good noise margin on long PCB traces."},{"question":"Does DSC1122BE2-312.5000T have an enable/disable function?","answer":"Yes — the part includes an Enable/Disable pin. When disabled, the output goes into a high-impedance state and the supply current drops to 22 mA max, saving power while keeping the oscillator core running for fast restart."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1122BE2-312.5000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122BE2-312.5000T when reusing this data.
