SI5340A-B03504-GM

Overview

The SI5340A-B03504-GM is a programmable clock generator from Skyworks Solutions, designed for ultra-low-jitter applications. It features four outputs capable of generating any frequency below 1028 MHz. The device supports multiple output types including CML, HCSL, LVCMOS, LVDS, and LVPECL. Key electrical parameters include a maximum input frequency of 750 MHz, a jitter specification of 90 fs, and an operating voltage range of 1.71 V to 3.47 V. It operates within a temperature range of -40°C to +85°C and is housed in a QFN-44 package.

Feature Summary

• Ultra-low jitter performance with 90 fs specification
• Four independent outputs supporting frequencies up to 1028 MHz
• Flexible output interface options: CML, HCSL, LVCMOS, LVDS, LVPECL
• Programmable architecture for custom frequency generation

Applications

• High-speed data communication systems requiring precise clocking
• Telecommunications infrastructure equipment
• Test and measurement instruments
• Networking switches and routers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix B03504 matches design requirements as it defines the internal configuration. Check current lifecycle status, as availability may be limited due to end-of-life conditions. Ensure ESD protection protocols are followed during handling of the QFN-44 package.

Selection Notes

Select this model when four low-jitter clocks are needed with flexible voltage levels. Compare against SI5340A-D-GM if generic programming is sufficient instead of fixed configuration. Verify that the 750 MHz max input frequency meets source clock constraints. Ensure the QFN-44 footprint aligns with PCB layout capabilities.

Part Context

This part belongs to the Si5340 family of MultiSynth clock generators. It shares core architecture with other variants like SI5340A-D-GM but differs in factory-programmed settings defined by the B03504 code. The family targets high-performance timing solutions requiring minimal phase noise across diverse output standards.

Replacement Considerations

Direct functional substitutes include other Si5340A variants such as SI5340A-D-GM, provided the fixed frequency configuration of B03504 is replaced by external programming. Cross-referencing pinouts and thermal characteristics is essential when substituting.
