It accepts an LVTTL or crystal input and delivers six differential clock outputs at up to 133 MHz. The 1:6 fanout and differential outputs make it the reference clock source for the CPU, memory controller, and PCI bus on those motherboards. ## Supply and temperature — fit for the intended environment The supply range is 3.135 V to 3.465 V. The operating temperature range is 0°C to 70°C. ## RoHS non-compliant — plan for compliance review This part is marked RoHS non-compliant, meaning it uses lead-bearing solder finish. For EU markets or any RoHS-restricted BOM, a compliance exemption or a waiver may be needed.","metaTitle":"Cypress CY28344PVC Frequency Synthesizer, 133 MHz, 48-SSOP","metaDescription":"Cypress CY28344PVC PLL frequency synthesizer for Intel 830M/845 chipsets. 133 MHz max, 3.3V supply, 1:6 differential outputs, 48-SSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"PLL":"Yes","Type":"Frequency Synthesizer","Input":"LVTTL, Crystal","Output":"Clock","Package":"Bulk","Mounting Type":"Surface Mount","Package / Case":"48-BSSOP (0.295\\\", 7.50mm Width)","Frequency - Max":"133MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.135V ~ 3.465V","Divider/Multiplier":"Yes/No","Number of Circuits":"2","Ratio - Input:Output":"1:6","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"48-SSOP","Differential - Input:Output":"No/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.94","stockQuantity":0,"priceTiers":[{"qty":102,"price":"$2.94000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/69e87e973951dd5eb7a46d07840032c2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY28344PVC obsolete or end-of-life?","answer":"No — the lifecycle status is Active, meaning Cypress (now Infineon) still lists it as a current product. No end-of-life notice or last-time-buy window has been issued. However, the target chipset (Intel 830M/845) is obsolete, so demand is low and the part may become harder to source through the factory channel over time."},{"question":"What is the replacement for CY28344PVC?","answer":"There is no direct pin-compatible replacement listed by the manufacturer. The closest functional peer in the Cypress portfolio is the CY2305SXI-1HT, but that is a zero-delay buffer with a single-ended output, not a differential clock synthesizer. For a form-fit-function substitute, review the Infineon (ex-Cypress) clock generator family for a PLL with 1:6 differential outputs in a 48-SSOP."},{"question":"Does CY28344PVC work with Intel 845 chipset?","answer":"Yes — the part was designed for the Intel 830M and 845 chipsets. It generates the required reference clocks for the CPU, memory controller hub, and I/O controller hub on those platforms. The 133 MHz maximum output covers the front-side bus speed of the 845 chipset."},{"question":"What is CY28344PVC's listed PLL status?","answer":"PLL is listed as Yes — this is a phase-locked loop frequency synthesizer, not a simple clock buffer or fanout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY28344PVC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY28344PVC when reusing this data.
