SI5338N-B01504-GM

Overview

The SI5338N-B01504-GM is a programmable quad clock generator from Skyworks Solutions. It synthesizes four independent output clocks with 0 ppm precision using MultiSynth technology. The device supports differential and single-ended outputs, including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats. Core supply voltage ranges from 1.71 V to 3.63 V, with typical operating current of 45 mA. Maximum input frequency reaches 710 MHz via differential inputs. Output frequencies span up to 710 MHz for differential drivers and 200 MHz for CMOS. Typical RMS jitter is 0.7 ps. The component operates within an ambient temperature range of –40 °C to +85 °C.

Feature Summary

• I2C/SMBus programmable interface for flexible configuration
• MultiSynth technology enabling zero ppm frequency accuracy on all outputs
• Independent output voltage support (1.5, 1.8, 2.5, or 3.3 V) per driver
• Glitchless frequency adjustment in 1 ppm steps via increment/decrement feature

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, package type, and pre-programmed factory settings. Confirm that the I2C pull-up voltage requirements align with the system design, particularly if operating below 2.5 V. Ensure ESD handling procedures are followed during assembly due to the sensitivity of the CMOS inputs.

Selection Notes

Select this model when independent clock synthesis with low jitter is required across multiple signal standards. Verify that the desired output frequencies fall within the supported ranges for the chosen output format (e.g., LVDS up to 710 MHz vs. CMOS up to 200 MHz). Check thermal resistance specifications if high load currents are expected at maximum frequencies.

Part Context

This component belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete crystal oscillators by providing any-frequency synthesis on four output drivers. The device integrates a phase-locked loop and multiple MultiSynth dividers to achieve precise frequency generation without external resonators for the output stages.

Replacement Considerations

Direct replacements within the same family include other Si5338 variants with different factory programming or output configurations. When substituting, ensure the new part supports the required output formats and frequencies. Verify compatibility with existing I2C addressing and register maps if custom programming is utilized.
