This qualifies it for under-hood and chassis-domain applications where the ambient temperature can reach 85°C."},{"question":"What supply voltage does the DSC1123AI2-312.5000T need?","answer":"The wide tolerance also helps if the supply has ripple or droop."},{"question":"Does the DSC1123AI2-312.5000T have an enable/disable pin?","answer":"Yes, the Enable/Disable function lets you hold the LVDS output in high-Z. When disabled, the supply current drops from 32 mA (max) to 22 mA (max), saving power in sleep or standby modes."},{"question":"What is the output type of the DSC1123AI2-312.5000T?","answer":"It outputs LVDS (Low-Voltage Differential Signaling) at 312.5 MHz. LVDS provides low noise and fast edge rates, making it a common choice for clocking high-speed ADCs, FPGAs, and SerDes interfaces."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1123AI2-312.5000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1123AI2-312.5000T when reusing this data.
