SI5338L-B04358-GM

Overview

The SI5338L-B04358-GM is a programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. The device supports differential and single-ended outputs including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. It operates from a 1.8 V, 2.5 V, or 3.3 V core supply with a typical current of 45 mA. Key electrical parameters include a maximum input frequency of 710 MHz, a typical phase jitter of 0.7 ps RMS, and an operating temperature range of -40 °C to +85 °C.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with 0 ppm accuracy.
• Low phase jitter performance of 0.7 ps RMS typical.
• Flexible input reference options: external crystal (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), or differential (5-710 MHz).
• Highly configurable output drivers supporting up to four differential or eight single-ended outputs.

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 applications.

Procurement Notes

Verify the specific ordering suffix B04358 against the manufacturer's official documentation to confirm factory-programmed NVM settings. Confirm package type and RoHS compliance status through the latest datasheet revision. Ensure I2C/SMBus interface voltage levels match the system design requirements for reliable programming.

Selection Notes

Select this component when low jitter and flexible frequency synthesis are required for multiple clock domains. Ensure the input reference source matches the supported formats (crystal, CMOS, or differential). Verify that the output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) align with the load requirements. Consider the 4x4 mm QFN-24 package constraints for PCB layout.
