The CY2280PVC-1 is a 100-MHz clock synthesizer and driver designed for Pentium II and similar processor-based motherboards. It operates with mixed voltage levels of 2.5V and 3.3V, providing four 2.5V CPU clock outputs, eight 3.3V PCI clock outputs, two 3.3V USB clock outputs, and three reference clocks at 14.318 MHz. The device features programmable spread spectrum clocking to reduce electromagnetic interference (EMI), with options for downspread modulation. It includes power management capabilities with pins for CPU stop, PCI stop, and power down, ensuring glitch-free transitions during operation. The CY2280 is housed in a compact 48-pin SSOP package, making it suitable for space-constrained applications. This product is ideal for engineers looking for a reliable clock solution for their PC designs.
