SI5338A-B01392-GM

Overview

The SI5338A-B01392-GM is a programmable clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. The device operates with a core supply of 1.8 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. Input frequencies range from 5 MHz to 710 MHz depending on the interface type. Configuration is managed via an I2C/SMBus-compatible serial interface.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis with 0 ppm precision on four output drivers
• Supports flexible input references: external crystal (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), and differential (5-710 MHz)
• Independently configurable output drivers support various signal formats and supply voltages (1.5, 1.8, 2.5, or 3.3 V)
• Features glitchless frequency adjustments in 1 ppm steps and independent phase adjustment with <20 ps accuracy

Applications

• Ethernet switch/router
• PCIe Gen1/2/3/4
• Processor and FPGA clocking
• Telecom line cards
• Fibre Channel, SAN

Procurement Notes

Verify the specific ordering suffix B01392 against the manufacturer's current documentation to confirm factory programming parameters. Ensure compatibility with I2C bus voltage levels if operating below 2.5 V by checking register settings. Confirm package integrity for the 24-QFN form factor during handling.

Selection Notes

Select this component when designing systems requiring multiple independent clock frequencies from a single source. Ensure the required output format (LVPECL, LVDS, etc.) and frequency range are supported by the specific driver configuration. Verify that the input reference source matches one of the supported types, such as differential or single-ended CMOS.

Part Context

This part belongs to the Si5338 family of I2C-programmable quad clock generators. The 'A' designation typically indicates the highest performance variant within the series, supporting up to 710 MHz output frequencies. The 'GM' suffix denotes the 24-lead QFN package option.

Replacement Considerations

Other variants within the Si5338 family, such as SI5338B or SI5338Q, offer similar functionality but may have different maximum output frequency limits (e.g., 350 MHz or 200 MHz). Verify that the replacement part supports the required maximum output frequency and output drive configurations.
