SI5338A-B01604-GM

Overview

The SI5338A-B01604-GM is a programmable quad clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports core supply voltages of 1.8, 2.5, or 3.3 V and operates within an ambient temperature range of –40 to +85 °C. The device features low phase jitter of 0.7 ps RMS typical and allows for glitchless frequency adjustments in 1 ppm steps. Outputs are configurable for LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats with independent voltage levels. It is housed in a 4 x 4 mm QFN-24 package.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four differential output drivers with 0 ppm precision.
• Low phase jitter of 0.7 ps RMS typical, compliant with PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS standards.
• Highly-configurable output drivers supporting up to four differential outputs, eight single-ended clock outputs, or combinations thereof.
• Independent frequency increment/decrement feature enables glitchless frequency adjustments in 1 ppm steps.

Applications

• PCIe Gen1/2/3/4
• Ethernet switch/router
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout compatibility and factory configuration settings. Ensure that the I2C pull-up voltage requirements align with the system design, particularly if operating below 2.5 V. Confirm moisture sensitivity level handling procedures during assembly as indicated in the datasheet.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single source. Verify that the desired output signal formats (LVPECL, LVDS, CMOS, etc.) match the available driver configurations. Ensure the input reference frequency falls within the supported ranges for the chosen input type (crystal, CMOS, or differential). Check thermal resistance specifications if operating at maximum load currents.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete crystal oscillators and frequency translators. The 'A' designation typically indicates the 710 MHz performance grade variant within the series. The 'GM' suffix denotes the 24-lead QFN package format.

Replacement Considerations

Direct replacements within the same family include other Si5338 variants such as SI5338A-B-GMR or SI5338Q-B-GMR, provided the frequency and output format requirements are met. Verify register compatibility and pinout alignment before substitution.
