SI5338A-B01316-GMR

Overview

The SI5338A-B01316-GMR is a programmable quad clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended formats 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 references range from external crystals (8–30 MHz) to differential inputs up to 710 MHz. Outputs are configurable for frequencies up to 710 MHz depending on the format.

Feature Summary

• MultiSynth technology enables independent, glitchless frequency synthesis with 0 ppm accuracy on four outputs.
• Supports flexible input references: external crystal, CMOS, SSTL/HSTL, and differential inputs up to 710 MHz.
• Configurable output drivers support LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats.
• Integrated spread spectrum capability with adjustable deviation (0.5% to 5.0%) and modulation rates.

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliant systems
• Ethernet switch/router and 1 GbE/10 GbE interfaces
• Processor and FPGA clocking solutions
• Broadcast video/audio timing distribution

Procurement Notes

Verify the specific factory configuration code 'B01316' against the manufacturer's ordering guide to confirm pre-programmed frequencies and pinout assignments. Confirm package marking matches the datasheet specifications for the Si5338 series. Ensure I2C pull-up voltages align with the selected core supply voltage for proper interface operation.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single IC. Verify that the target output formats (LVPECL, LVDS, etc.) match the load requirements. Check that the input reference source falls within the supported frequency ranges for the chosen input type. Ensure the application requires the low jitter performance specified in Table 12.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The suffix 'GMR' indicates a tape-and-reel packaging format suitable for automated surface-mount assembly. The 'A' designation typically refers to the specific silicon revision or performance grade within the product line.

Replacement Considerations

Direct replacements must maintain the QFN-24 package and MultiSynth architecture. Verify compatibility with existing I2C programming files generated by ClockBuilder Pro software. Ensure substitute devices support the same output voltage levels and jitter specifications required by the design.
