SI5338N-B05007-GMR

Overview

The SI5338N-B05007-GMR is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency up to 710 MHz on four independent output drivers with zero ppm precision. The device supports flexible input references including external crystals (8–30 MHz), CMOS, SSTL/HSTL, and differential inputs up to 710 MHz. Outputs are configurable for LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL formats. Key electrical parameters include a core supply voltage of 1.8 V, 2.5 V, or 3.3 V, a typical operating current of 45 mA, and a typical phase jitter of 0.7 ps RMS. It operates within an ambient temperature range of –40 °C to +85 °C.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with true zero ppm accuracy.

• Highly-configurable output drivers supporting LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL signal formats.
• I2C/SMBus compatible interface for programming, supported by ClockBuilder Pro software.

Applications

• PCIe Gen1/2/3/4 systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific factory-programmed NVM configuration associated with the B05007 suffix against the target design requirements. 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 independent frequency synthesis across multiple outputs is required without external crystal oscillators. Ensure the input reference source matches the supported formats (crystal, CMOS, or differential). Validate that the output load capacitance and drive strength requirements are met by the configurable output buffers.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'N' designation typically indicates a custom factory-programmed variant with specific frequencies stored in non-volatile memory. The '-GMR' suffix denotes tape-and-reel packaging suitable for automated surface-mount assembly processes.

Replacement Considerations

Direct pin-to-pin replacements within the same family require matching the output frequency configuration and jitter performance. Verify compatibility with existing I2C addressing and control logic if replacing a different Si5338 variant.
