Product Summary

The SKY535xx series is low jitter and pin-compatible with buffers from other clock manufacturers.

The lineup includes 4/8/10 differential channels, and the clock format (LVPECL, LVDS, HCSL) can be selected for each bank.

The built-in LDO provides high PSRR, helping to reduce the number of external components, and supports an operating temperature range of -40 to +95°C (maximum board temperature 105°C).

Example applications include jitter-sensitive high-speed clock distribution, network synchronization, and FPGA/communication systems.

It can be easily replaced with a pin-compatible product currently in use, with low jitter and improved functionality.

It is also possible to configure a high-precision clock tree by combining it with Skyworks' NetSymc™ product line.
