SI53306-B-GM

Clock Buffers, Drivers Overview

The SI53306-B-GM is a universal fanout clock buffer from the Si5330x family, designed for low-jitter clock distribution. It features four differential outputs and accepts any-format inputs including LVPECL, LVDS, CML, HCSL, and LVCMOS. The device operates within a frequency range of 1 MHz to 725 MHz with a maximum propagation delay of 1075 ps. Powered by a core voltage (VDD) between 1.71 V and 3.63 V, it delivers ultra-low additive jitter typically around 50 fs rms. Integrated LDOs provide high power supply rejection ratio (PSRR), simplifying design in noisy environments. The component is housed in a 16-QFN package.

Clock Buffers, Drivers Feature Summary

• Universal input support for LVPECL, LVDS, CML, HCSL, and LVCMOS formats
• Four differential outputs with configurable signal levels
• Ultra-low additive jitter performance of 50 fs rms
• Built-in LDOs for enhanced power supply noise rejection

Clock Buffers, Drivers Applications

• Clock distribution networks requiring format translation
• Redundant clocking systems
• High-speed digital interfaces

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging and configuration. Confirm that the application environment remains within the specified operating temperature range of -40 °C to +85 °C. Ensure power supply decoupling meets the datasheet recommendations to maintain optimal jitter performance.

Clock Buffers, Drivers Selection Notes

Select this part when a single-input, four-output buffer is required without the need for an input multiplexer. Verify that the output drive strength and termination requirements match the load impedance. Check if the synchronous output enable feature is necessary, as this variant supports individual output control.

Clock Buffers, Drivers Part Context

This component belongs to the Si5330x family of universal buffers. Unlike variants such as the SI53301 or SI53302, the SI53306 does not include a 2:1 input mux. It provides a simplified solution for distributing a single clock source to multiple destinations while supporting various logic families through pin-strappable output configurations.

Clock Buffers, Drivers Replacement Considerations

Direct functional replacements within the same family include the SI53307-B-GM, which offers two outputs instead of four. For applications requiring input switching, the SI53301-B-GM or SI53302-B-GM may be considered, though they require different pinouts and configuration.
