That max frequency puts it solidly in Ku-band (12-18 GHz), K-band (18-27 GHz), and the lower edge of Ka-band satellite downlinks — think point-to-point microwave backhaul, VSAT terminal LOs, and test-equipment local oscillators that need to sweep past 20 GHz without a multiplier stage. The 26.5 GHz ceiling is the RF output of the internal VCO and N-divider path; above that you need an external doubler or a separate mmWave VCO. Below it, this one chip replaces a discrete PLL + VCO + loop-filter combo that would eat board space and double the BOM count. ## Integer-N vs Fractional-N — the phase-noise vs step-size tradeoff The dual-mode architecture lets the designer pick the loop bandwidth and step size independently. In Integer-N mode, the phase noise at a given offset is set by the reference frequency and the N-divider value — a clean 100 MHz reference gives lower in-band noise than a 10 MHz one, but the step size is locked to the reference. Fractional-N mode breaks that tie: you can run a 100 MHz reference and still get kilohertz channel spacing by modulating the divider modulus, at the cost of fractional spurs that the loop filter must suppress. For a wideband sweep generator or a test instrument that needs sub-kHz resolution, Fractional-N is the natural choice. For a fixed-frequency LO in a radio where phase noise at 10 kHz offset is the link-budget killer, Integer-N with a high reference gives the cleanest output. The ADF41513BCPZ supports both on the same die, so the same PCB layout serves either mode — the firmware selects the mode at power-up. ## Supply rail and temperature — what the 3.3V ±5% and -40 to 105°C mean on the bench The supply range is 3.135V to 3.465V — a tight 3.3V ±5% window. The charge pump current and VCO tuning slope are calibrated to this nominal; if the 3.3V rail droops to 3.0V under load, the VCO gain (Kvco) shifts and the loop bandwidth moves off the design target. A dedicated LDO feeding this rail, with less than 10 mV ripple at 1 MHz, is the standard practice. ## Input logic and package — CML/CMOS reference and the 24-LFCSP footprint The reference input accepts both CML and CMOS levels without external level translation. CML is the clean choice for a high-frequency reference (above 500 MHz) because the differential swing reduces common-mode noise coupling into the PLL. CMOS works with a standard TCXO or crystal oscillator up to a few hundred MHz — the internal input buffer handles the single-ended-to-differential conversion. The 24-LFCSP (4x4) package has an exposed thermal pad on the bottom; the PCB footprint must include a ground-plane island with at least four thermal vias (0.3 mm drill, filled or tented) to pull heat out of the die. The pad is also the RF ground return for the output stage — a poor via stitch adds inductance that degrades the output phase noise above 10 GHz. ## Active lifecycle and compliance — sourcing posture It is ROHS3 compliant (fully lead-free, no RoHS exemptions). The part ships in a JEDEC tray, not tape-and-reel; for high-volume pick-and-place, the tray-to-reel transfer is a standard distributor service.","metaTitle":"ADF41513BCPZ PLL Synthesizer, 26.5 GHz","metaDescription":"ADF41513BCPZ PLL synthesizer from Analog Devices, 26.5 GHz max frequency, Integer-N/Fractional-N, 3.135-3.465V supply, -40 to 105°C, 24-LFCSP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"PLL":"Yes","Type":"Integer-N/Fractional-N","Input":"CML, CMOS","Output":"Clock","Package":"Tray","Mounting Type":"Surface Mount","Package / Case":"24-WFQFN Exposed Pad, CSP","Frequency - Max":"26.5GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.135V ~ 3.465V","Divider/Multiplier":"Yes/Yes","Number of Circuits":"1","Ratio - Input:Output":"2:1","Operating Temperature":"-40°C ~ 105°C","Supplier Device Package":"24-LFCSP (4x4)","Differential - Input:Output":"Yes/No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$63.38","priceTiers":[{"qty":1,"price":"$63.38000","currency":"USD"},{"qty":10,"price":"$59.53600","currency":"USD"},{"qty":25,"price":"$57.61560","currency":"USD"},{"qty":80,"price":"$53.39038","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ADF41513BCPZ/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between ADF41513BCPZ and ADF41513BCPZ-RL7?","answer":"The ADF41513BCPZ ships in a tray, while the ADF41513BCPZ-RL7 ships in tape-and-reel.
