SI5338A-B05709-GMR

Overview

The SI5338A-B05709-GMR is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent output drivers with zero ppm accuracy. The device supports differential and single-ended formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. Input references range from 5 MHz to 710 MHz. Key electrical parameters include a core supply voltage of 1.8 V, 2.5 V, or 3.3 V, typical operating current of 45 mA, and typical phase jitter of 0.7 ps RMS. It operates within an ambient temperature range of –40 °C to +85 °C.

Feature Summary

• I2C/SMBus programmable with ClockBuilder Pro software
• Low phase jitter of 0.7 ps RMS typical
• Independent glitchless frequency adjustment in 1 ppm steps
• Supports spread spectrum modulation (0.5% to 5.0%)

Applications

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

Procurement Notes

Verify the specific ordering suffix B05709 against the manufacturer's official documentation to confirm the programmed frequency plan and output configuration. Confirm package availability and lead times through authorized distributors as stock levels vary.

Selection Notes

Select this component for designs requiring low-jitter synthesis across multiple disparate frequencies. Ensure the required output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) match the load requirements. Verify input signal compatibility with the supported CMOS, differential, or crystal options.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces multiple discrete oscillators in high-speed digital systems. The 'GMR' suffix indicates tape and reel packaging suitable for automated surface-mount assembly.

Replacement Considerations

Direct pin-compatible replacements within the same family include SI5338A-B-GM or SI5338Q-B-GMR. Verify that the substitute part number matches the required frequency plan and output drive strength specifications.
