SI5338A-B06088-GMR

Overview

The SI5338A-B06088-GMR is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports input frequencies up to 710 MHz and generates outputs with 0 ppm precision. The device features low phase jitter of 0.7 ps RMS typical, configurable output formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL, and operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V. It is housed in a compact 4 x 4 mm QFN-24 package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with zero ppm accuracy.
• Supports flexible input references including external crystals (8–30 MHz), CMOS (5–200 MHz), and differential inputs (up to 710 MHz).
• Configurable output drivers support various signal formats: LVPECL/LVDS (up to 710 MHz), HCSL (up to 250 MHz), and CMOS (up to 200 MHz).
• Features glitchless frequency adjustments via independent increment/decrement and programmable spread spectrum generation.

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliant timing
• Ethernet switch/router clocking
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix B06088 against the manufacturer's current datasheet to confirm factory-programmed frequency and format configurations. Ensure I2C pull-up voltage compatibility if operating below 2.5 V by checking register settings. Confirm moisture sensitivity handling requirements for the QFN-24 package during assembly.

Selection Notes

Select this component when designing systems requiring multiple independent clock frequencies from a single IC. Ensure the required output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) match the load requirements. Verify that the input reference source matches one of the supported types: crystal, single-ended CMOS, or differential.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'A' indicates the specific silicon revision or performance grade, while 'B06088' denotes a factory-programmed configuration. The '-GMR' suffix specifies the tape-and-reel packaging format for surface-mount assembly.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other Si5338 variants with different factory programming codes (e.g., SI5338A-Bxxxxx-GMR). Ensure the replacement part supports the required output frequencies and formats specified in the design.
