SI5338A-B05145-GMR

Overview

The SI5338A-B05145-GMR is a programmable clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with frequencies up to 710 MHz. The device operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, with individual output supplies configurable between 1.5 V and 3.3 V. Key electrical parameters include a typical phase jitter of 0.7 ps RMS, a maximum input frequency of 710 MHz, and an operating temperature range of -40 °C to +85 °C.

Feature Summary

• MultiSynth™ technology enables zero ppm precision frequency synthesis on four independent outputs.
• 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).
• Configurable output formats include LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL.
• Features glitchless frequency adjustments in 1 ppm steps and independent phase adjustment with <20 ps accuracy.

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant systems.
• Ethernet switch/router and 1 GbE/10 GbE interfaces.
• Processor and FPGA clocking solutions.
• Telecom line cards and MSAN/DSLAM/PON equipment.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape/reel specifications. Ensure compatibility with I2C/SMBus interface requirements for system integration. Confirm that the selected voltage levels align with the device's recommended operating conditions for both core and output supplies.

Selection Notes

Select this component when low jitter performance below 1 ps RMS is required for high-speed serial links. Ensure the design accommodates the 4x4 mm QFN-24 package footprint and thermal characteristics. Verify that the application requires independent output voltage levels or specific signal formats supported by the Si5338 family.

Part Context

This part belongs to the Si5338 family of quad clock generators. It is designed to replace multiple discrete crystal oscillators or frequency translators. The device integrates a PLL and MultiSynth synthesizers within a compact form factor, offering flexibility for complex timing architectures in data communication and networking applications.

Replacement Considerations

Consult the official Skyworks substitution guide for verified compatible parts. Generic replacements may not support the same jitter performance or MultiSynth configuration capabilities. Verify pinout and register compatibility before implementing any alternative components.
