The PLL block includes a bypass path, letting you feed a clean reference straight through when phase noise is more critical than frequency multiplication. Maximum output frequency is 312.5 MHz, which covers the reference clock range for most Gigabit Ethernet PHYs, FPGA transceivers, and ADC/DAC sampling clocks. ## Supply rail and output drive — what to plan for Supply voltage range is 2.97V to 3.63V, nominally a 3.3V rail. No separate 1.8V or 2.5V supply is needed — the output logic levels are generated from the same core supply, so your power-tree design stays simple. The differential input and output capability allows long PCB traces or cable runs with common-mode noise rejection, useful when the clock source is on a separate card. Package is a 48-lead LFCSP with exposed pad, 7x7 mm body. The exposed paddle must be soldered to a ground plane for both thermal relief and a low-inductance return path — a standard via-in-pad layout works. The 0.50 mm pitch demands a 4-layer board for fan-out; two-layer boards will struggle to route all seven outputs cleanly. ## Production status and sourcing posture ROHS3 compliant, so it passes the current EU material restrictions without an exemption.","metaTitle":"AD9574BCPZ Clock Generator IC - Analog Devices - PLL with","metaDescription":"AD9574BCPZ clock generator IC from Analog Devices.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"PLL":"Yes with Bypass","Input":"Clock","Output":"CMOS, HCSL, HSTL, LVDS","Package":"Tray","Mounting Type":"Surface Mount","Package / Case":"48-WFQFN Exposed Pad, CSP","Frequency - Max":"312.5MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"2.97V ~ 3.63V","Divider/Multiplier":"Yes/Yes","Number of Circuits":"1","Ratio - Input:Output":"2:7","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"48-LFCSP (7x7)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.19","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.19000","currency":"USD"},{"qty":10,"price":"$9.20700","currency":"USD"},{"qty":25,"price":"$8.77880","currency":"USD"},{"qty":80,"price":"$7.62263","currency":"USD"},{"qty":230,"price":"$7.28009","currency":"USD"},{"qty":440,"price":"$6.63773","currency":"USD"},{"qty":945,"price":"$5.78124","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8315cdc60c9cbaba8b1ff42833b4bd9d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional equivalent to AD9574BCPZ?","answer":"The AD9516-4BCPZ is a clock generator with PLL and 14 outputs, but its max frequency is 2.95 GHz and it lacks the PLL bypass feature. The AD9552BCPZ has a PLL with bypass and runs to 900 MHz, but its input:output ratio is 2:2 and it does not support differential inputs.
