SI5338N-B06154-GMR

Overview

The SI5338N-B06154-GMR is a programmable quad clock generator from Skyworks Solutions. It synthesizes four independent output clocks with zero ppm frequency accuracy 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 precision on four independent drivers.
• 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 and phase 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 and audio timing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pinout configuration and factory programming settings. Ensure the I2C pull-up voltage matches the system requirements, as register adjustments may be necessary for voltages below 2.5 V.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source. Confirm that the target output signal format (LVDS, HCSL, etc.) and voltage levels are supported by the specific output driver configuration. Validate that the input reference frequency falls within the supported range for the chosen mode.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'N' suffix typically denotes a specific factory-programmed configuration variant within the series, distinguishing it from blank or differently configured parts like the 'F' or 'Q' variants.

Replacement Considerations

Direct replacements must match the 24-QFN package and support the same output configurations. Verify compatibility with existing I2C addresses and register maps if swapping between different Si533x sub-families.
