SI5338N-B06177-GMR

Overview

The SI5338N-B06177-GMR is a programmable quad clock generator manufactured by Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. The device supports differential and single-ended outputs, accommodating formats such as LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. It operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. Configuration is performed via an I2C/SMBus interface.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with 0 ppm accuracy.
• Supports flexible input references including external crystals (8-30 MHz), CMOS (5-200 MHz), and differential inputs up to 710 MHz.
• Features independently configurable output drivers supporting LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats.
• Includes glitchless frequency adjustments in 1 ppm steps and independent phase adjustment with <20 ps resolution.

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout assignments and factory programming configurations. Ensure the I2C pull-up voltage aligns with the supported range of 1.71 V to 3.63 V for proper bus compatibility.

Selection Notes

Select this component when designing systems requiring multiple independent clock frequencies from a single package. Verify that the required output signal formats and supply voltages match the device's capabilities. Confirm that the input reference frequency falls within the supported ranges for the chosen configuration mode.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The family is characterized by its ability to replace multiple discrete crystal oscillators with a single highly-configurable IC. The specific model indicates a particular factory-programmed configuration for the output frequencies and formats.

Replacement Considerations

Direct replacements within the Si5338 family require matching the specific factory-programmed output frequencies and formats. Generic Si5338 devices must be reprogrammed using ClockBuilder Pro software to replicate the exact electrical characteristics and timing parameters of the original part.
