SI5340A-B03603-GM

Overview

The SI5340A-B03603-GM is a programmable clock generator from the Skyworks Si5340 family, housed in a QFN-44 package. It provides four differential outputs capable of generating any frequency up to 1028 MHz with an input range up to 750 MHz. The device delivers ultra-low jitter performance of 90 fs rms and supports multiple output formats including LVDS, LVPECL, LVCMOS, CML, and HCSL. Operating on 1.8 V or 3.3 V supplies within a -40°C to +85°C temperature range, it integrates MultiSynth technology for precise frequency synthesis without phase error.

Feature Summary

• Generates any combination of output frequencies from any input frequency using proprietary MultiSynth fractional synthesizer technology
• Ultra-low jitter performance of 90 fs rms with 0 ppm error across all outputs
• Supports flexible output formats: LVDS, LVPECL, LVCMOS, CML, and HCSL with programmable signal amplitude
• Configurable via I2C/SPI interfaces or factory pre-programmed using ClockBuilderPro software

Applications

• High-speed data communication systems requiring precise clock distribution
• Telecommunications infrastructure equipment
• Test and measurement instruments
• Industrial automation control systems

Procurement Notes

Verify the specific suffix B03603 against official Skyworks documentation to confirm the exact frequency plan and output configuration. Confirm current availability status as this part number may be subject to limited supply or end-of-life conditions depending on production cycles.

Selection Notes

Select this component when sub-100 fs jitter is required for high-speed serial links. Ensure the design accommodates the QFN-44 thermal requirements. Verify that the desired output frequencies fall within the 100 Hz to 1028 MHz range for differential outputs.

Part Context

This device belongs to the Si5340/41 family of any-frequency, any-output clock generators. It serves as a replacement for multiple discrete oscillators and clock buffers, consolidating clock tree functionality into a single chip. The Si5340 variant specifically offers four outputs compared to the ten available in the Si5341.

Replacement Considerations

Direct replacements include other Si5340A variants with different suffixes for customized frequency plans. For higher output counts, consider the Si5341 series. Cross-reference with Si5340B if lower frequency limits (350 MHz) are acceptable.
