Clock/Timing - Clock Buffers, Drivers

5P90011PGGI8 (5P90011PGGI8) is a high speed clock/timing buffer designed for digital equipment system applications. It is used for clock buffering and transmission, generating low-skew low-jitter output clock signals from its one stable input clock source. This buffer transfers serial data from one high speed clock source to multiple low speed destinations on a Printed Circuit Board (PCB).

Application Field

5P90011PGGI8 is designed to buffer high speed clock signals from one source to multiple destinations, and can support frequencies up to 8.5 Gbps with up to 16-bit buffer output. This buffer can provide up to 16 outputs, maintaining perfect synchronization while powering down the data-streams in the system.

It supports a wide range of applications, such as: Network & Communication Systems, cache-/memory controllers, data-/storage-controllers, display, audio & video solutions, home theater systems, mobile multimedia and desktop PCs, game consoles and more.

Working Principle

The 5P90011PGGI8 clock buffer has a single, stable clock source and provides fan-out clock signals to multiple destinations. The buffer offers two differential clock input ports, supporting source clocks from 0.7V to 3.3V. There is an optional power-down pin (PDIN) for controlling the power of the buffer.

The 5P90011PGGI8 buffer incorporates a PLL (phase-locked loop) to ensure high performance synchronization of the source and destination clocks. The buffer also has two output ports (OCMP and OREF) for generating reference and cascade clock signals for buffering the inputs.

In addition to the PLL, the 5P90011PGGI8 has a low-jitter oscillator to generate a precise, low-jitter clock signal with up to 8.5 GHz clock rate. The high-speed oscillator is capable of providing a clean output while maintaining a low latency.

Conclusion

The 5P90011PGGI8 is an advanced clock buffer designed to synchronize multiple clock sources and fan out clock signals to multiple destinations. The buffer supports clock rates up to 8.5 Gbps and offers multiple output signals with low-skew and low-jitter. This clock buffer is suitable for a wide range of applications including networking, storage and multimedia devices.
