• Networking equipment: Found in routers, switches, and other networking devices to ensure synchronized data transfer.
• Graphics cards: Distributes clock signals to the GPU and memory chips.
• High-speed backplanes: Buffers and distributes clock signals across backplanes in server and communication systems.
• Test and measurement equipment: Used in oscilloscopes, logic analyzers, and other instruments requiring precise timing.

Features

• Zero delay: Minimizes the delay between the input clock and the output clocks.
• Low skew: Ensures that all output clocks are synchronized with minimal timing difference.
• Multiple outputs: Provides multiple buffered clock outputs to drive different components.
• Wide operating frequency range: Supports a wide range of input clock frequencies.
• Low jitter: Maintains low jitter performance to preserve clock signal integrity.

Benefits
