It operates from a 3V to 3.6V supply — nominally 3.3V — and includes a PLL bypass mode that lets you feed the input straight through for test or low-jitter paths. Maximum output frequency is 125 MHz, which covers most DDR, PCI, and gigabit Ethernet reference clock trees in commercial equipment. ## What the 1:16 fanout and 125 MHz ceiling mean for the BOM The 125 MHz maximum frequency sets the upper bound. Stay at or below 125 MHz and the PLL holds lock across the 0°C to 70°C commercial temperature range. ## Package and footprint — 48-TSSOP, 6.10 mm body The CDC2516DGGR comes in a 48-lead TFSOP with a 6.10 mm body width. It is surface-mount only. ## Lifecycle and sourcing posture That means no LTB risk for new designs. Both are the same silicon, so a BOM can accept either with a packaging note.","metaTitle":"CDC2516DGGR PLL Clock Driver, 125 MHz, 1:16 LVTTL, 48-TSSOP","metaDescription":"Texas Instruments CDC2516DGGR PLL clock driver with bypass, 125 MHz max, 1:16 fanout, LVTTL I/O, 3.3V supply, 48-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PLL":"Yes with Bypass","Type":"PLL Clock Driver","Input":"LVTTL","Output":"LVTTL","Package":"Bulk","Mounting Type":"Surface Mount","Package / Case":"48-TFSOP (0.240\\\", 6.10mm Width)","Frequency - Max":"125MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Divider/Multiplier":"No/No","Number of Circuits":"1","Ratio - Input:Output":"1:16","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"48-TSSOP","Differential - Input:Output":"No/No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.58","stockQuantity":0,"priceTiers":[{"qty":46,"price":"$6.58000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/87c64d6b239b46be8c9d82b25ee95f24.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CDC2516DGGR available via RFQ confirmation?","answer":"Stock levels change daily.
