SI5338N-B05519-GM

Overview

The SI5338N-B05519-GM is an I2C-programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four output drivers with 0 ppm precision. The device supports flexible input references including external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz). Outputs support LVPECL, LVDS, HCSL, CMOS, SSTL, and 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 a temperature range of –40 °C to +85 °C.

Feature Summary

• I2C/SMBus programmable interface for configuration
• MultiSynth technology enabling independent, any-frequency synthesis on four outputs
• Low phase jitter of 0.7 ps RMS typical
• Highly configurable output drivers supporting multiple signal formats and voltages

Applications

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

Procurement Notes

Verify the specific factory-programmed NVM configuration associated with the B05519 suffix against system requirements. Confirm that the QFN-24 package dimensions and thermal characteristics align with the PCB land pattern design. Ensure the I2C bus voltage levels are compatible with the selected core supply voltage.

Selection Notes

Select this component when zero ppm frequency accuracy and low jitter are critical for high-speed serial links. Verify that the required output frequencies and formats (LVPECL, LVDS, etc.) fall within the specified ranges for each driver. Consider the power consumption of 45 mA typical when designing the power delivery network.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'N' suffix indicates custom factory programming via Non-Volatile Memory (NVM). The 'GM' suffix denotes the tape and reel packaging format. The device replaces multiple discrete oscillators in complex digital systems.

Replacement Considerations

Direct pin-to-pin replacements within the Si5338 family may require reprogramming if the NVM configuration differs. Verify compatibility with existing I2C control logic and ensure that the replacement part supports the same output formats and frequency ranges.
