SI53344-B-GM

Clock Buffers, Drivers Overview

The SI53344-B-GM is a low-jitter LVDS fanout clock buffer from the Si5334x family, manufactured by Skyworks Solutions. It features a universal any-format input stage supporting LVPECL, LVDS, CML, HCSL, and LVCMOS signals via a 2:1 input multiplexer. The device provides ten LVDS outputs operating within a frequency range of dc to 1250 MHz. Key electrical specifications include a typical additive jitter of 50 fs rms, a maximum propagation delay of 1050 ns, and an output-to-output skew of 50 ps. It operates on a single supply voltage ranging from 1.71 V to 3.63 V and is housed in a 32-QFN package.

Clock Buffers, Drivers Feature Summary

• Universal any-format input with 2:1 mux for LVPECL, LVDS, CML, HCSL, and LVCMOS
• Ten LVDS outputs with ultra-low additive jitter (typical 50 fs rms)
• Wide frequency range from dc to 1250 MHz
• Built-in LDOs for high power supply noise rejection

Clock Buffers, Drivers Applications

• Clock and data distribution systems
• Redundant clocking architectures
• High-speed digital interface synchronization

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and configuration. Ensure compatibility with the system's input signal format and required output count before procurement. Cross-reference the datasheet revision date to confirm technical parameters.

Clock Buffers, Drivers Selection Notes

Select this component when a fixed LVDS output format is required alongside flexible input compatibility. The 2:1 input mux allows selection between two clock sources. Verify that the application supports the dc to 1250 MHz frequency range and requires ten buffered LVDS channels.

Clock Buffers, Drivers Part Context

This part belongs to the Si53340-45 family of low-jitter LVDS fanout buffers. It shares the same functional architecture as the SI53340-B-GM but differs in output count, providing ten outputs instead of four. It is designed to pair with Si534x clocks and Si5xx oscillators for complete clock tree solutions.

Clock Buffers, Drivers Replacement Considerations

The SI53340-B-GM serves as a direct alternative within the same family, offering identical input and performance characteristics but with only four LVDS outputs.
