SI53326-B-GMR

Clock Buffers, Drivers Overview

The SI53326-B-GMR is a low-jitter LVPECL fanout clock buffer from the Si5332x family, manufactured by Skyworks Solutions Inc. It features a 2:1 selectable input multiplexer and provides ten LVPECL outputs from a single-ended LVCMOS input format. The device supports a wide frequency range from DC up to 200 MHz. Key electrical specifications include a typical additive jitter of 50 fs rms, an operating supply voltage range of 2.38 V to 3.63 V, and an ambient operating temperature range of –40 °C to +85 °C. It utilizes built-in LDOs for high power supply noise rejection.

Clock Buffers, Drivers Feature Summary

• Ten LVPECL outputs with a 2:1 selectable input mux
• Single-ended LVCMOS input format support
• Ultra-low additive jitter performance (typical 50 fs rms)
• Built-in LDOs for enhanced power supply noise rejection

Clock Buffers, Drivers Applications

• Clock distribution in noisy environments
• Redundant clocking architectures
• Low-jitter clock tree implementation

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the selected variant matches the required input format constraints.

Clock Buffers, Drivers Selection Notes

Select this component when a single-ended LVCMOS source must drive multiple LVPECL loads within a 200 MHz frequency limit. The integrated 2:1 mux allows for seamless switching between two independent clock sources. Verify that the application environment remains within the specified –40 °C to +85 °C operating temperature range.

Clock Buffers, Drivers Part Context

This part belongs to the Si53320–28 family of fixed-format LVPECL buffers. While other members of the series support universal any-format inputs or higher frequencies up to 1250 MHz, the SI53326 is specifically configured for single-ended LVCMOS inputs and operates up to 200 MHz.

Clock Buffers, Drivers Replacement Considerations

The SI53326-B-GM is listed as a parameter-equivalent alternative in distributor databases. Verify pin compatibility and electrical specifications before substitution.
