SI5338A-B05001-GM

Overview

The SI5338A-B05001-GM is a programmable quad clock generator from Skyworks Solutions. It synthesizes four independent output clocks with zero ppm frequency accuracy using MultiSynth technology. The device supports a core supply voltage of 1.8 V, 2.5 V, or 3.3 V and operates within an ambient temperature range of -40 °C to +85 °C. Maximum input and output frequencies reach 710 MHz for differential signals. Typical phase jitter is 0.7 ps RMS, and the typical core supply current is 45 mA.

Feature Summary

• MultiSynth technology enables any-frequency synthesis on four independent output drivers with 0 ppm precision.
• 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).
• Independent output drivers support various signal formats such as LVPECL, LVDS, HCSL, CMOS, and SSTL/HSTL with configurable supply voltages.
• Features glitchless frequency adjustments in 1 ppm steps and independent phase adjustment with <20 ps resolution.

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

Procurement Notes

Verify the specific factory configuration code associated with the B05001 suffix against the manufacturer's ordering guide. Confirm that the QFN-24 package dimensions and thermal characteristics meet the target PCB land pattern requirements. Ensure I2C pull-up voltages are compatible with the selected bus standard.

Selection Notes

Select this component when low jitter synthesis below 710 MHz is required. Verify that the desired output formats (LVPECL, LVDS, etc.) align with the available driver configurations. Check if the internal NVM programming capability meets the system's power-on initialization needs without external configuration memory.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It utilizes patented MultiSynth architecture to replace multiple discrete oscillators. The device integrates a PLL and multiple synthesizers into a compact 4x4 mm QFN package, designed for high-density board layouts.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Evaluate other SKUs within the Si5338 series based on specific frequency ranges and output format requirements.
