SI5338A-B01319-GM

Overview

The SI5338A-B01319-GM is an I2C-programmable quad clock generator from Skyworks Solutions. It synthesizes any frequency on four output drivers using MultiSynth technology, achieving zero ppm precision. The device supports a core supply of 1.8 V, 2.5 V, or 3.3 V and operates within a temperature range of –40 to +85 °C. Key electrical parameters include a maximum input frequency of 710 MHz, typical phase jitter of 0.7 ps RMS, and a typical core supply current of 45 mA.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis with 0 ppm accuracy on four differential output drivers
• Low phase jitter performance of 0.7 ps RMS typical
• Flexible input reference options including external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz)
• Independently configurable outputs supporting LVPECL/LVDS (up to 710 MHz), HCSL (up to 250 MHz), CMOS (up to 200 MHz), and SSTL/HSTL (up to 350 MHz)

Applications

• PCIe Gen 1/2/3/4 common clock and Gen 3 SRNS compliant systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific B-code suffix against the manufacturer's ordering guide to confirm factory-programmed frequencies and configurations. Confirm package type and operating temperature range match design requirements before procurement.

Selection Notes

Select this component for designs requiring low-jitter, flexible clock synthesis across multiple domains. Ensure the required output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) are supported by the target loads. Utilize ClockBuilder Pro software for accurate configuration of frequencies and spread spectrum settings.

Part Context

This part belongs to the Si5338 family of high-performance clock generators. It replaces multiple discrete oscillators in complex digital systems. The 'B' code indicates a specific factory-programmed configuration, while 'GM' denotes the 24-lead QFN package.

Replacement Considerations

Direct pin-to-pin replacements within the same family may require reprogramming via ClockBuilder Pro. Verify that alternative parts support the same output formats and jitter specifications.
