SI5338K-B04065-GMR

Overview

The SI5338K-B04065-GMR is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential inputs up to 710 MHz and offers flexible output formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. The device operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V with a typical current consumption of 45 mA. It features low phase jitter, high precision synthesis, and I2C/SMBus control for configuration.

Feature Summary

• Four independent output drivers supporting any frequency synthesis with zero ppm accuracy
• Flexible input reference options: external crystal (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), or differential (5-710 MHz)
• Configurable output formats: LVPECL/LVDS/CML (up to 710 MHz), HCSL (up to 250 MHz), CMOS (up to 200 MHz), SSTL/HSTL (up to 350 MHz)
• Independent output voltage levels per driver: 1.5 V, 1.8 V, 2.5 V, or 3.3 V

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
• Telecom line cards and MSAN/DSLAM/PON applications

Procurement Notes

Verify the specific factory programming associated with the B04065 suffix against the target design requirements using ClockBuilder Pro software. Confirm that the QFN-24 package dimensions and thermal characteristics align with the PCB land pattern specifications provided in the datasheet.

Selection Notes

Select this component when four independent clock signals with varying frequencies or formats are required from a single source. Ensure the input reference signal matches one of the supported types (crystal, CMOS, or differential). Verify that the required output voltage levels (1.5 V to 3.3 V) are compatible with the load devices.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'K' suffix typically denotes specific pin control or output enable configurations, while 'B04065' indicates a factory-programmed variant with fixed frequency and format settings. The 'GMR' suffix specifies the tape and reel packaging option.

Replacement Considerations

Direct replacements within the Si5338 family may require reprogramming via ClockBuilder Pro if the new part is not pre-configured. Ensure the replacement part supports the same input frequency range and output drive capabilities.
