The PLL core includes a bypass mode: when the loop is open, the VCO runs free, which is useful for open-loop modulation or sweeping past the loop-bandwidth corner where the PLL's phase noise would otherwise dominate. Differential inputs accept LVDS or LVPECL levels, and the outputs are also differential — the signal stays in the current-mode logic domain end to end, so the layout sees a controlled 100-Ω differential impedance rather than a single-ended 50-Ω trace. The supply rail spans 3 V to 5.4 V — wide enough to run off a 3.3-V or 5-V regulated bus without an extra LDO, though the PLL charge-pump and VCO core noise floor are sensitive to supply ripple, so a clean rail matters more here than on a digital part. No second-source cross-reference is maintained — the part is the primary order code for this function.","metaTitle":"STUW81300TR RF Frequency Synthesizer, 16 GHz","metaDescription":"Active STUW81300TR RF frequency synthesizer, 16 GHz max, PLL with bypass, LVDS/LVPECL I/O, 36-VFQFN.

The T suffix ships in trays; the TR suffix ships on tape and reel. The electrical and thermal specifications are identical. For a pick-and-place line already set up for reel feed, the TR is the direct fit; for a prototype run or low-volume build where trays are easier to handle, the T works without any board change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STUW81300TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STUW81300TR when reusing this data.
