SI5338N-B05167-GMR

Overview

The SI5338N-B05167-GMR is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V and accepts flexible input references up to 710 MHz. Key electrical parameters include a maximum output frequency of 710 MHz, typical phase jitter of 0.7 ps RMS, and a core supply current of 45 mA.

Feature Summary

• MultiSynth technology enables zero ppm precision synthesis for four independent clocks
• Supports flexible input references: external crystal (8-30 MHz), CMOS, SSTL/HSTL, and differential inputs
• Configurable output drivers support various signal formats and independent voltage levels (1.5V, 1.8V, 2.5V, 3.3V)
• Glitchless frequency adjustment via independent increment/decrement features

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliant systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Telecom line cards and MSAN/DSLAM/PON applications

Procurement Notes

Verify the specific ordering suffix B05167 against the manufacturer's official documentation to confirm factory-programmed configuration settings. Ensure compatibility with I2C/SMBus interface requirements and check for moisture sensitivity handling instructions during storage and assembly.

Selection Notes

Select this component when designing systems requiring low-jitter clock synthesis with flexible output formats. Verify that the required output frequencies fall within the supported ranges for the chosen driver format (e.g., up to 710 MHz for LVDS/LVPECL). Confirm that the system power budget accommodates the typical 45 mA core supply current.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces multiple discrete crystal oscillators in complex digital systems. The device integrates a PLL and MultiSynth dividers to generate precise clock signals from a single reference source.

Replacement Considerations

Direct pin-to-pin replacements within the same package may exist within the Si5338 family, but functional equivalence depends on matching the specific pre-programmed frequency and format configurations defined by the B05167 suffix.
