The 1:5 fanout ratio lets one reference clock feed multiple downstream devices without adding a separate fanout buffer. The PLL includes a bypass mode, meaning you can route the input clock directly to the outputs for test or low-jitter bypass operation. This is useful during board bring-up or when you need to compare the PLL-generated clock against the source. ## Supply voltage and temperature envelope The part operates from a 3.135V to 3.465V supply, a standard 3.3V ±5% rail. The PLL's internal VCO and loop filter are sensitive to supply noise; expect to place a 0.1 µF ceramic decoupling capacitor within 2 mm of each supply pin. Temperature range is commercial grade: 0°C to 70°C ambient. This restricts the part to indoor, temperature-controlled equipment — office networking gear, consumer set-top boxes, or bench test instruments. Do not use in outdoor telecom cabinets or under-hood automotive without a full thermal analysis and a qualified industrial-grade alternative. ## Package and footprint considerations Housed in a 16-lead TSSOP with a 4.40 mm body width. The footprint is standard for low-pin-count clock generators; a two-layer board with a ground plane under the package is adequate for most designs. The supplier device package is listed as 16-TSSOP. The part is — not tape-and-reel — so plan for manual placement or a tube feeder if you are using an automated pick-and-place line. ## Sourcing status and lifecycle RoHS compliance is marked as non-compliant. Verify your assembly house's exemption policy for lead-bearing finishes — this part may require a waiver or a separate RoHS-compliant variant if your product must meet EU RoHS requirements.","metaTitle":"CY22394FCT Clock Generator – Infineon, PLL, 400 MHz","metaDescription":"CY22394FCT from Infineon Technologies: PLL clock generator, 200 MHz (CMOS) / 400 MHz (PECL) max output, 1:5 fanout, 3.3V supply, 16-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"PLL":"Yes with Bypass","Type":"Clock Generator","Input":"LVTTL, Crystal","Output":"CMOS, PECL","Package":"Bulk","Mounting Type":"Surface Mount","Package / Case":"16-TSSOP (0.173\\\", 4.40mm Width)","Frequency - Max":"200MHz, 400MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.135V ~ 3.465V","Divider/Multiplier":"Yes/No","Number of Circuits":"1","Ratio - Input:Output":"1:5","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"16-TSSOP","Differential - Input:Output":"No/No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.38","stockQuantity":0,"priceTiers":[{"qty":126,"price":"$2.38000","currency":"USD"}]},"links":{"datasheetUrl":"https://rocelec.widen.net/view/pdf/gwelfqw7uf/CYPRS07437-1.pdf?t.download=true&u=5oefqw","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY22394FCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY22394FCT when reusing this data.
