The Infineon CY27430FLTXS is a Spread Spectrum Clock Generator with a PLL that can be bypassed. It accepts Clock or Crystal inputs and provides a wide range of outputs including CML, HCSL, LVCMOS, LVDS, and LVPECL. Supporting frequencies of 250MHz and 700MHz, it is designed to reduce EMI in electronic systems. Packaged in a 48-VFQFN, it operates from -40°C to 105°C.

  • EMI Reduction: Spread spectrum technology lowers electromagnetic interference for regulatory compliance.
  • Versatile Outputs: Supports CML, HCSL, LVCMOS, LVDS, and LVPECL for broad compatibility.
  • PLL Bypass Option: Allows direct clocking when spread spectrum is not needed.
  • Wide Temperature Range: Operates from -40°C to 105°C for industrial and automotive use.

EMI Reduction in Consumer Electronics

Spread spectrum clocking reduces electromagnetic interference (EMI) in devices like TVs, set-top boxes, and gaming consoles, helping meet regulatory standards.

PC & Laptop Motherboards

Generates spread spectrum clocks for CPUs, memory, and I/O interfaces to minimize EMI and improve signal integrity.

Networking & Communication
