SI5338K-B05615-GM

Overview

The SI5338K-B05615-GM is a programmable clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four output drivers. It supports differential inputs up to 710 MHz and offers independent output voltage configurations of 1.5, 1.8, 2.5, or 3.3 V. The device operates with a core supply of 1.8, 2.5, or 3.3 V, drawing a typical current of 45 mA. It features low phase jitter of 0.7 ps RMS typ, glitchless frequency adjustments in 1 ppm steps, and independent phase adjustment with <20 ps accuracy. Packaged in a 4x4 mm QFN-24, it functions within an ambient temperature range of -40 to +85 °C.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with 0 ppm precision.
• Flexible input reference options 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 formats such as LVPECL/LVDS (up to 710 MHz), HCSL, CMOS, and SSTL/HSTL.
• Configurable spread spectrum (SSC) on any output with frequencies from 5 to 350 MHz and modulation rates from 33 to 63 kHz.

Applications

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

Procurement Notes

Verify the specific ordering suffix for the SI5338K-B05615-GM against the manufacturer's latest documentation to confirm factory programming parameters. Ensure compatibility with I2C/SMBus interfaces and check for moisture sensitivity handling requirements during assembly.

Selection Notes

Select this component when designing systems requiring zero-delay mode via external feedback or independent frequency increment/decrement capabilities. Consider the 4x4 mm QFN package constraints and verify that the required output voltage levels (1.5V to 3.3V) align with the target load specifications.

Part Context

This part belongs to the Si5338 family of I2C-programmable quad clock generators. The 'K' variant typically denotes specific pinout or feature sets compared to other series members like 'A', 'B', or 'Q'. It replaces multiple discrete oscillators by providing four independent clock outputs from a single reference source.

Replacement Considerations

Direct replacements within the Si5338 family include variants such as SI5338A, SI5338B, or SI5338Q. Verify that the substitute part number matches the required output frequencies, jitter performance, and I2C configuration files before integration.
