It takes a single CMOS input and regenerates eight CMOS outputs phase-aligned to the reference, with the PLL cleaning up jitter and skew. The part includes an internal divider and multiplier, so you can synthesize a different output frequency from the input — useful for generating a multiple of a reference clock without an external VCXO. ## 80 MHz ceiling and the 5V supply reality Rated for 80 MHz maximum, the CY7B992-2JCT covers the common clock speeds for 100Base-T Ethernet, PCI, and mid-range processor buses. The supply range is 4.5V to 5.5V — a straight 5V part. It is not 3.3V tolerant on the input or output, so if your board runs a 3.3V clock tree you need a level translator or a different buffer. The 1:8 ratio means a single input drives eight loads, which saves a second buffer stage in a moderate fanout design. ## Package and temperature — where it fits Housed in a 32-PLCC with J-leads (11.43x13.97 mm body), the part is surface-mount but uses a PLCC footprint — not the same as a QFP or SOIC. The operating temperature range is 0°C to 70°C, which limits it to commercial indoor equipment: servers, telecom line cards, test gear, and office networking. Not rated for industrial or automotive environments. ## Lifecycle and sourcing posture It remains a current-production part, so the supply channel is the standard franchise distribution, not the surplus market. The part is RoHS non-compliant, which matters if your assembly line is restricted to lead-free solder; verify your reflow profile and exemption status before committing the BOM.","metaTitle":"Cypress CY7B992-2JCT PLL Clock Driver, 80 MHz, 1:8 Fanout","metaDescription":"Cypress CY7B992-2JCT PLL-based zero-delay fanout buffer. 80 MHz max, 1:8 CMOS outputs, 5V supply, 32-PLCC.
