SI53360-B-GTR

Clock Buffers, Drivers Overview

The Skyworks SI53360-B-GTR is a low-jitter, LVCMOS fanout clock buffer featuring eight outputs and a frequency range from DC to 200 MHz. It utilizes advanced CMOS technology with built-in LDOs for high PSRR performance, eliminating the need for external filtering components. The device supports dual-bank configurations and a 2:1 input MUX option. Key electrical parameters include an additive jitter of 120 fs RMS, propagation delay of 4.5 ns maximum, and output-to-output skew of 125 ps maximum. Operating voltage ranges from 1.71 V to 3.63 V, with an operating temperature range of –40 °C to +85 °C.

Clock Buffers, Drivers Feature Summary

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix '-B-' against the manufacturer's ordering guide to confirm the exact pinout and configuration variant. Confirm RoHS compliance status via the Skyworks Certificate of Conformance before integration. Ensure ESD handling precautions are strictly followed during assembly due to sensitivity ratings.

Clock Buffers, Drivers Selection Notes

Select this component when eight buffered LVCMOS outputs are required within a 200 MHz bandwidth. The built-in LDOs simplify design by reducing board-level filtering needs. Verify that the supply voltage matches the 1.8 V, 2.5 V, or 3.3 V requirements and that the thermal resistance characteristics fit the PCB layout constraints.

Clock Buffers, Drivers Part Context

This part belongs to the Si5336x family of low-jitter LVCMOS fanout buffers. Other members include the Si53361 (8 outputs, QFN), Si53362 (12 outputs, dual bank), and Si53365 (8 outputs, single input). All share similar core technologies but differ in package type, output count, and power supply configurations.

Clock Buffers, Drivers Replacement Considerations

Direct replacements within the same family include the Si53361-B-xxxxx-GT for identical functionality in a different package. Cross-family substitution requires verifying output count, jitter specifications, and voltage compatibility.
