SI5361B-A15695-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5361B-A15695-GMR is an 18-output jitter attenuator and clock multiplier featuring one DSPLL and one MultiSynth. It supports a maximum output frequency of 1.3 GHz with ultra-low phase jitter under 55 fs typical. The device accepts differential inputs up to 1000 MHz or LVCMOS inputs up to 250 MHz. It operates on core voltages of 1.71 V to 1.89 V and peripheral voltages of 3.14 V to 3.47 V. The component is housed in a 72-lead QFN package (10x10 mm) and functions within an ambient temperature range of -40°C to +95°C.

• 100/200/400/600/800G networking line cards
• Datacenter switches

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm interface requirements and factory programming status. Ensure the supply chain source provides valid RoHS compliance documentation. Confirm that the received components match the specified 72-QFN package dimensions and thermal characteristics before integration into the design.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a single DSPLL architecture combined with one MultiSynth is sufficient for the target frequency plan. Compare against the Si5361A variant if additional MultiSynths are required for complex distribution networks. Verify that the 1.3 GHz maximum output frequency meets the system requirements, as higher frequencies require the Si5361H variant.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5361 family of jitter attenuators from Skyworks Solutions. It shares the same 72-QFN footprint and basic electrical specifications as the Si5361A and Si5361C variants. The primary distinction lies in the internal PLL and MultiSynth configuration, which defines the available output flexibility and synchronization capabilities for different system architectures.
