The 8521AYI-03LN enables clock synchronization and signal restoration across systems that run at disparate data rates and voltage levels. They provide high-accuracy skew and jitter performance while reducing power consumption and supporting a variety of interface protocols and different clock enable formats. 8521AYI-03LN can also provide hot-swap and power-fail mute functions to minimize the risk of unexpected system reset associated with power supply transients. This clock buffer is mainly used for telecom, ethernet, and server applications.

The 8521AYI-03LN buffers are designed for the synchronization of system clocks, digital data and timing control signals. They are ideal for connecting baseband and datacom systems to meet the needs of varying complex application architectures. 8521AYI-03LN clock buffers are used to drive digital logic and can be configured with the following features:

• Programmable output driver current
• Auto Skew and Jitter compensation
• Programmable output slew rate
• Programmable output skew
• Programmable output slew rate
• High-accuracy clock generation and buffering
• Programmable flow-through mode for improved noise reduction

8521AYI-03LN clock buffers can accept inputs from several different sources like 24MHz crystal oscillators, LVCMOS devices, PCI clocks, transceivers, synthesizers, and embedded PLLs. The input clock is then buffered and distributed to the various devices in the system via 3.3V/2.5V level output banks. The device provides both differential and single-ended output banks to allow maximum flexibility and optimum timing control in a wide range of applications.

The programmable output driver current on the 8521AYI-03LN clock buffers is designed to achieve high-speed skew and jitter performance while still providing low-power consumption. The output driver also has adjustable slew rate, and the support for flow-through mode provides noise reduction for high-speed and high-accuracy clock synchronization.

The 8521AYI-03LN is also capable of providing hot-swap and power-fail mute functions, which further reduces the risk of unexpected system reset associated with power supply transients. Additionally, the device can communicate with external control logic to control output supply levels, provide clock gating, and support complex clock control, generation and buffering.

In summary, the 8521AYI-03LN is a flexible and low power clock buffer designed for high-speed wires and digital systems. With support for various synchronization protocols, hot-swap and power-fail mute functions, and programmable output skews, the device offers an excellent solution for telecom, ethernet, and server applications requiring high-accuracy clock synchronization and signal restoration.
