SI53305-B-GM

Clock Buffers, Drivers Overview

The SI53305-B-GM is a universal fanout clock buffer with up to 10 differential outputs, operating within a frequency range of 1 MHz to 725 MHz. It features an integrated 2:1 input multiplexer for redundant clocking and supports any-format inputs including LVPECL, LVDS, CML, HCSL, and LVCMOS. The device delivers ultra-low additive jitter of 50 fs rms and includes built-in LDOs for high power supply noise rejection. Outputs are configurable via pin-strapping to support multiple signal formats independently across two banks.

Clock Buffers, Drivers Feature Summary

• Ultra-low additive jitter performance of 50 fs rms
• Integrated 2:1 input multiplexer with glitchless switching capability
• Universal input termination supporting LVPECL, LVDS, CML, HCSL, and LVCMOS
• Flexible output drivers with independent format selection per bank

Clock Buffers, Drivers Applications

• Clock distribution in noisy environments requiring low jitter
• Redundant clocking systems utilizing dual input sources
• Format translation between different clock standards
• High-speed digital system synchronization

Clock Buffers, Drivers Procurement Notes

Verify the package type matches the design requirements, as this component utilizes a 44-QFN footprint. Confirm that the ordering suffix corresponds to the desired packaging configuration, noting that adding an 'R' denotes tape and reel options. Ensure compatibility with RoHS-6 compliance standards during procurement.

Clock Buffers, Drivers Selection Notes

Select this model when a 2:1 input mux and individual output enable control are required. It is suitable for applications needing up to 10 differential outputs with independent format translation capabilities. Consider the Si5330x family alternatives if specific output counts or mux configurations differ from these specifications.

Clock Buffers, Drivers Part Context

This component belongs to the Si5330x family of universal low-jitter clock buffers. It shares functional similarities with other members like the Si53302 and Si53304 but is distinct in its specific output count and mux integration. The family is designed for end-to-end clock tree performance when paired with Skyworks jitter attenuators and oscillators.

Clock Buffers, Drivers Replacement Considerations

Public confirmed substitute part numbers include SI53302-B-GM and SI53304-B-GM. Verify pin compatibility and output configuration requirements before substitution.
