SI5338N-B04890-GMR

Overview

The SI5338N-B04890-GMR is a programmable clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four output drivers. It supports differential and single-ended outputs with configurable formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, with independent output voltage settings per driver. Key electrical parameters include a maximum input/output frequency of 710 MHz, typical phase jitter of 0.7 ps RMS, and an operating temperature range of -40°C to +85°C.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis with 0 ppm precision on four output drivers.
• Configurable output drivers support up to four differential, eight single-ended, or mixed configurations.
• Low phase jitter performance of 0.7 ps RMS typical.
• Flexible input reference options including external crystals (8-30 MHz), CMOS, SSTL/HSTL, and differential inputs.

Applications

• Ethernet switch/router
• PCIe Gen1/2/3/4
• Broadcast video/audio timing
• Processor and FPGA clocking
• MSAN/DSLAM/PON

Procurement Notes

Verify the specific ordering suffix B04890 against the manufacturer's official documentation to confirm pre-programmed frequency and configuration data. Ensure compatibility with I2C/SMBus interfaces for device programming. Confirm package type is 24-QFN and check for moisture sensitivity handling requirements during storage and assembly.

Selection Notes

Select this component when low-jitter, flexible clock generation is required for high-speed digital interfaces. Verify that the required output frequencies fall within the supported ranges for the chosen signal format (e.g., LVDS up to 710 MHz, CMOS up to 200 MHz). Ensure the system design accommodates the 4x4 mm QFN package and provides appropriate power supply decoupling for the 1.8 V, 2.5 V, or 3.3 V core voltage.

Part Context

The SI5338 series is designed to replace multiple crystal oscillators or function as a frequency translator. It integrates a PLL and MultiSynth synthesizers in a compact form factor. The N suffix typically denotes a specific variant within the Si5338 family, often related to output configuration or pinout variations, requiring datasheet verification for exact functional differences compared to other suffixes like A or G.

Replacement Considerations

Direct replacements must match the 24-QFN package and I2C interface. Verify if alternative part numbers from the same family offer identical pre-programmed configurations or if reprogramming via ClockBuilder Pro software is feasible. Check for pin-to-pin compatibility and ensure thermal characteristics remain within acceptable limits for the application environment.
