PLL clock distribution for server platforms
The CY2280PVC-1 is a PLL-based clock generator designed for Intel CPU server motherboards, accepting a single clock input and distributing it across 19 outputs (1:19 ratio) at up to 100 MHz. The wide supply range of 2.375V to 3.465V lets it run from either a 2.5V or 3.3V rail without an extra regulator.
Fanout and frequency ceiling
With a 1:19 fanout and 100 MHz maximum output, this part handles clock distribution to multiple loads — memory controllers, PCIe root complexes, or I/O hubs — from a single reference. The non-differential I/O (No/No) means it drives single-ended clock lines, not LVDS or HCSL, so the board routing is simpler but the noise margin is lower than a differential pair would offer.
Temperature grade and package constraints
The 48-BSSOP (7.50 mm width) package is a surface-mount SSOP with 0.635 mm pitch; the wide body helps with manual inspection but takes up more board area than a QFN of similar pin count.
Lifecycle and compliance flags
The RoHS compliance status is non-compliant, which is a hard block for any build targeting EU RoHS exemption-free production. If your BOM requires RoHS, this part needs a waiver or a functional replacement.
