SI53321-B-GMR Description

Short technical summary and product information.

The Skyworks Solutions SI53321-B-GMR is a high-performance clock buffer designed for clock/data distribution and redundant clocking applications. It operates at frequencies up to 1.25 GHz and supports various input formats including LVPECL, LVDS, CML, HCSL, and LVCMOS, outputting LVPECL signals.

 

This device features a 2:10 ratio, meaning it can take two input signals and distribute them to ten outputs. It operates over a wide voltage range of 2.375V to 3.63V and is designed for surface mount installation in a 32-QFN (5x5mm) package with an exposed pad. The operating temperature range is -40°C to 85°C.

 

Key features include built-in LDOs for high PSRR performance, simplifying clock distribution in noisy environments. The SI53321-B-GMR is suitable for applications requiring low-jitter clock signals and flexible input format translation.
