SI5338M-B05693-GMR

Overview

The SI5338M-B05693-GMR 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 for LVDS/LVPECL/CML formats, 350 MHz for SSTL/HSTL, and 250 MHz for HCSL. The device operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, with independently configurable output voltages. It features low phase jitter (0.7 ps RMS typ), glitchless frequency adjustments in 1 ppm steps, and spread spectrum capabilities. Configuration is managed via an I²C/SMBus interface.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with 0 ppm precision.
• Low phase jitter of 0.7 ps RMS typical, compliant with PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS standards.
• Flexible input references including external crystals (8–30 MHz), CMOS (5–200 MHz), and differential inputs (5–710 MHz).
• Highly configurable output drivers supporting LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats.

Applications

• Ethernet switch/router clocking
• PCIe Gen1/2/3/4 common clock generation
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, temperature range, and shipping configuration. Ensure compatibility with the I²C bus voltage levels used in the target system, as the device supports standard and fast mode operations within specified voltage ranges.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single IC. Consider the output format requirements (LVDS vs. CMOS) and maximum frequency needs (up to 710 MHz for differential outputs). Verify that the input reference source matches the supported frequency ranges for crystal, CMOS, or differential inputs.

Part Context

The SI5338 series replaces multiple discrete oscillators with a single programmable solution. The Si5338 family offers space-saving 4x4 mm QFN packaging and low power consumption (45 mA typical). It is designed for high-performance timing applications requiring precise frequency synthesis and low jitter across various industry standards.

Replacement Considerations

Direct replacements within the Si5338 family may require reprogramming via ClockBuilder Pro software to match specific frequency and output configurations. Verify pinout compatibility and electrical specifications such as supply voltage and jitter performance before substitution.
