This is the part you reach for when a single clock source needs to drive multiple loads without signal degradation, common in telecom line cards, industrial controllers, and legacy backplane timing trees. The 32-PLCC package with J-leads (11.43 x 13.97 mm body) is a through-hole-compatible surface-mount footprint that still sees heavy use in socketed or rework-friendly designs. ## 80 MHz fanout — what it means for the clock tree The 8:8 ratio means the part buffers eight input signals to eight outputs each, or can be configured as a 1:8 fanout buffer depending on the application. At 80 MHz, the propagation delay and skew between outputs are tight enough to keep a multi-drop clock bus within timing budget for most 33 MHz PCI, 50 MHz Ethernet MAC, or 66 MHz memory controller interfaces. The PLCC-32 package's J-leads offer a lower profile than DIP but still allow socket mounting for field serviceability — a consideration in telecom central-office gear where uptime drives the board architecture. ## Active, but watch the RoHS flag The catch is RoHS non-compliance — this part uses lead-bearing solder or plating, which means it cannot be used in designs requiring RoHS exemption-free assembly. For legacy builds that already have a leaded process qualified, this is not a blocker; for new designs targeting EU or California RoHS compliance, you will need to source a tin-lead compatible alternative or qualify a RoHS-compliant variant (if one exists in the family). ## Sourcing and supply reality The PLCC-32 package is still widely manufactured, so lead times tend to track the industry average for mature logic parts — typically 8 to 14 weeks from factory order, with spot availability through independent distributors for smaller quantities. The RoHS non-compliance narrows the buyer pool, which can actually improve availability for those who can accept leaded devices. Pricing is quoted per order; volume breaks are available above reel quantities.","metaTitle":"CY7B992-5JC Clock Buffer/Driver, 8:8 Fanout, 80 MHz, 32-PLCC","metaDescription":"Cypress CY7B992-5JC clock buffer/driver with 8:8 input-to-output ratio, 80 MHz max frequency, in 32-PLCC (J-Lead) package.","metaKeywords":null},"attributes":{"series":"*","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Type":"Buffer/Driver","Series":"*","Package":"Tube","Mounting Type":"Surface Mount","Package / Case":"32-LCC (J-Lead)","lifecycle_stage":"eol_hot","Ratio - Input:Output":"8:8","Supplier Device Package":"32-PLCC (11.43x13.97)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.62","stockQuantity":0,"priceTiers":[{"qty":29,"price":"$10.62000","currency":"USD"}]},"links":{"datasheetUrl":"https://www.infineon.com/cms/en/about-infineon/company/contacts/support/?utm_source=cypress&utm_medium=referral&utm_campaign=202110_globe_en_all_integration-files","sourceUrl":null},"ai":{"faq":[{"question":"Does CY7B992-5JC have a RoHS compliant version?","answer":"This specific order code (CY7B992-5JC) is marked RoHS non-compliant.
