SI5338C-B06036-GM

Overview

The SI5338C-B06036-GM is a programmable clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize four independent output clocks with zero ppm frequency accuracy. It supports differential and single-ended outputs including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats. The device operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, with independently configurable output voltages. Key electrical parameters include a maximum input frequency of 710 MHz, typical phase jitter of 0.7 ps RMS, and an operating temperature range of -40 °C to +85 °C.

Feature Summary

• MultiSynth™ technology enables any-frequency synthesis with 0 ppm precision across four independent drivers.
• Supports flexible input references: external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).
• Features glitchless frequency adjustments via independent increment/decrement and phase adjustment with <20 ps resolution.
• Configurable spread spectrum modulation on any output with frequencies from 5 to 350 MHz.

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliant systems
• Ethernet switch/router and 1 GbE/10 GbE interfaces
• Processor and FPGA clocking solutions
• Broadcast video/audio timing infrastructure

Procurement Notes

Verify the specific configuration code B06036 against the official Skyworks ClockBuilder Pro software or datasheet ordering information to ensure correct frequency and format settings. Confirm package type is QFN-24 and check for moisture sensitivity handling requirements during assembly.

Selection Notes

Select this component when low jitter (<1 ps RMS) and high precision (0 ppm) are required for multiple asynchronous clock domains. Ensure the design accommodates the 4x4 mm QFN-24 footprint and provides appropriate thermal relief given the junction-to-ambient resistance of 37 °C/W.

Part Context

This part belongs to the Si5338 family of I2C-programmable quad clock generators. The 'C' suffix typically denotes a specific performance tier or output frequency limit within the series, while 'GM' indicates the tape and reel packaging option for surface-mount assembly.

Replacement Considerations

Direct pin-compatible replacements within the same family may include other Si5338 variants with different configuration codes. Verify that alternative parts support the required output voltage levels and jitter specifications for the target application.
