SI5338L-B06239-GM

Overview

The SI5338L-B06239-GM is a programmable quad 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, while individual output buffers support voltages of 1.5 V, 1.8 V, 2.5 V, or 3.3 V. Key electrical parameters include a typical RMS jitter of 0.7 ps, a maximum input frequency of 710 MHz, and a maximum output frequency of 710 MHz. It is housed in a 4x4 mm QFN-24 package.

Feature Summary

• MultiSynth™ technology enables independent, zero ppm precision synthesis on four output drivers.
• 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 drivers support LVPECL/LVDS (up to 710 MHz), HCSL (up to 250 MHz), CMOS (up to 200 MHz), and SSTL/HSTL (up to 350 MHz).
• 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.
• Broadcast video/audio timing applications.

Procurement Notes

Verify the specific ordering suffix B06239 against the manufacturer's current documentation to confirm factory programming details. Ensure compatibility with I2C/SMBus interface requirements for system integration. Check for moisture sensitivity handling instructions prior to assembly.

Selection Notes

Select this component when low jitter (0.7 ps typ) and high-frequency synthesis up to 710 MHz are required. Ensure the design accommodates the 4x4 mm QFN-24 footprint and provides appropriate thermal relief. Verify that the target application supports the specified core voltage range of 1.8 V to 3.3 V.
