SI5338M-B04513-GM

Overview

The SI5338M-B04513-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 with frequencies up to 710 MHz. The device operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. It includes flexible input references, spread spectrum capabilities, and I2C/SMBus programming via ClockBuilder Pro software.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers
• Low phase jitter of 0.7 ps RMS typical for high-precision timing applications
• Flexible input reference options including external crystal (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential (5–710 MHz)
• Highly-configurable output drivers supporting LVPECL, LVDS, HCSL, CMOS, SSTL, HSTL, and CML formats

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant systems
• Ethernet switch/router clocking
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards and MSAN/DSLAM/PON equipment

Procurement Notes

Verify the specific factory-programmed NVM configuration associated with the B04513 suffix, as this part number represents a custom frequency set. Confirm package type is 24-QFN (4x4 mm) and check RoHS compliance status. Ensure I2C pull-up voltages match the system design, noting that register 27 must be written if the bus voltage is below 2.5 V.

Selection Notes

Select this component when zero ppm frequency accuracy is required across multiple outputs. Ensure the target frequencies fall within the supported ranges: LVPECL/LVDS/CML up to 710 MHz, HCSL up to 250 MHz, and CMOS up to 200 MHz. Verify that the input reference source matches one of the supported types (crystal, CMOS, or differential). Consider power consumption, which varies by output format and load capacitance.

Part Context

This part belongs to the Si5338 family of I2C-programmable quad clock generators. The 'M' indicates a specific output driver configuration or speed grade, while 'B04513' denotes a unique factory-programmed NVM content defining the clock frequencies and settings. The '-GM' suffix indicates a lead-free, halogen-free RoHS-compliant package in a tray.

Replacement Considerations

Direct replacements within the same family include other Si5338 variants with different NVM codes (e.g., SI5338A, SI5338B, SI5338C, SI5338D, SI5338K, SI5338Q) depending on the required frequency plan. Ensure the replacement part supports the same output formats and voltage levels.
