SI53362-B-GMR

Clock Buffers, Drivers Overview

The SI53362-B-GMR is a low-jitter, LVCMOS fanout clock buffer featuring dual banks of six outputs each. It supports frequency ranges from DC to 200 MHz and utilizes Skyworks advanced CMOS technology for guaranteed low additive jitter (120 fs RMS), low skew, and low propagation delay variability. The device includes built-in LDOs for high PSRR performance, eliminating the need for external components. It operates with supply voltages between 1.71 V and 3.63 V and functions within an ambient temperature range of –40 °C to +85 °C.

Clock Buffers, Drivers Feature Summary

• Dual-bank architecture providing up to 12 LVCMOS outputs from LVCMOS inputs.
• Built-in LDOs deliver high PSRR performance for robust operation in noisy environments.
• Low additive jitter specification of 120 fs RMS across the operating frequency range.
• Integrated 2:1 input MUX option allowing selection between two clock sources via CLK_SEL.

Clock Buffers, Drivers Applications

• Clock and data distribution systems requiring low jitter performance.
• Redundant clocking applications utilizing the dual-input MUX capability.
• End-to-end clock tree designs paired with Skyworks oscillators or generators.

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 through the official Certificate of Conformance provided by Skyworks Solutions. Ensure that the procurement channel provides valid traceability for the component batch.

Clock Buffers, Drivers Selection Notes

Select the SI53362-B-GMR when dual independent output banks are required for separate power domains or load isolation. Verify that the application voltage requirements align with the supported 1.8 V, 2.5 V, or 3.3 V LVCMOS levels. Consider the 24-QFN package dimensions and thermal relief pad requirements during PCB layout design.

Clock Buffers, Drivers Part Context

This component belongs to the Si5336x family of low-jitter LVCMOS fanout buffers, which also includes the Si53360, Si53361, and Si53365 models. While other family members offer single-bank configurations with eight outputs, the Si53362 is distinctively designed with dual banks of six outputs each to support complex clock distribution topologies.
