SI5338N-B06174-GMR

Overview

The SI5338N-B06174-GMR is a programmable quad clock generator from Skyworks Solutions. It synthesizes four independent output clocks with zero ppm precision using MultiSynth technology. The device supports differential and single-ended outputs, including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V and accepts inputs up to 710 MHz. Key electrical parameters include a typical RMS jitter of 0.7 ps, a maximum input frequency of 710 MHz, and a maximum output frequency of 710 MHz for differential signals. It is housed in a 24-lead QFN package.

Feature Summary

• MultiSynth technology enables any-frequency synthesis with 0 ppm accuracy on four independent outputs.
• Supports flexible output formats: LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL.
• Low phase jitter performance with a typical RMS value of 0.7 ps.
• Programmable via I2C/SMBus interface with glitchless frequency adjustment capabilities.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout configuration and factory programming settings. Ensure the I2C pull-up voltage compatibility matches the system design, particularly if operating below 2.5 V. Confirm thermal management requirements based on the QFN-24 package characteristics and ambient operating conditions.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source with low jitter. Verify that the desired output signal formats (LVDS, LVPECL, etc.) and voltage levels (1.5 V to 3.3 V) are supported by the specific output drivers. Check input frequency constraints, as differential inputs support up to 710 MHz while single-ended CMOS inputs are limited to 200 MHz.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'N' suffix typically denotes a specific factory-programmed configuration or pinout variant within the series. The 'GMR' suffix indicates tape-and-reel packaging. Other variants in the family may differ in pre-programmed frequencies or output enable configurations.

Replacement Considerations

Direct replacements must be from the Si5338 family with compatible pinouts and factory programming. Verify that alternative part numbers support the same output formats and jitter specifications. Cross-reference the specific ordering suffix to ensure functional equivalence in terms of programmed frequencies and control pin assignments.
