SI53322-B-GMR Description

Short technical summary and product information.

The Skyworks Solutions SI53322-B-GMR is a high-performance fanout clock buffer designed for efficient clock and data distribution. It operates at frequencies up to 1.25 GHz and supports multiple input formats including CML, HCSL, LVCMOS, LVDS, and LVPECL. The device features one circuit with a 1:2 output-to-input ratio and LVPECL outputs, making it suitable for demanding timing applications.

This buffer is built with integrated LDOs for high PSRR performance, simplifying clock distribution in noisy environments. It offers an output enable option for control. The SI53322-B-GMR is available in a 16-QFN (3x3 mm) package and is designed for surface mount applications. It operates over a temperature range of -40°C to 85°C.

The Si53320-28 family, to which this part belongs, is known for its ultra-low additive jitter characteristics of 50 fs rms. These buffers can be paired with other Skyworks clock generators and oscillators for complete clock tree solutions.
