Supplier Device Package 8-SOIC

The Cypress CY2302SI-1 is a Frequency Multiplier and Zero Delay Buffer with an integrated PLL. It accepts LVCMOS or LVTTL inputs and provides LVCMOS outputs up to 133MHz. With 1 circuit in an 8-SOIC package, it operates from -40°C to 85°C, making it suitable for automotive and industrial applications.

  • Zero Delay Buffer: Ensures output clocks are phase-aligned with input, reducing timing errors.
  • Frequency Multiplication: Generates higher frequencies from lower references, saving crystal costs.
  • Wide Temperature Range: -40°C to 85°C for harsh environments.
  • Small 8-SOIC Package: Minimizes PCB footprint.

Processor Clock Generation

Multiply a low-frequency reference to generate high-speed clocks for CPUs and memory controllers.

Zero Delay Buffering

Align output clocks with input, minimizing skew for synchronous systems.

Networking Equipment

Provide clean clocks for Ethernet PHYs and switches, ensuring reliable data transfer.

FPGA Systems

Generate multiple clock domains from a single source, simplifying board design.

Automotive Electronics

Wide temperature range supports engine control units and infotainment systems.
