SI5338F-B04077-GM

Overview

The SI5338F-B04077-GM is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports core supply voltages of 1.8 V, 2.5 V, or 3.3 V and operates within an ambient temperature range of –40 °C to +85 °C. The device features low phase jitter of 0.7 ps RMS typical, flexible input references up to 710 MHz, and independently configurable outputs supporting formats such as LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. It is housed in a compact 4 x 4 mm QFN-24 package.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis with zero ppm precision on four differential output drivers.
• Flexible input reference options including external crystals (8–30 MHz), CMOS (up to 200 MHz), and differential inputs (up to 710 MHz).
• Independently configurable output drivers support various signal formats (LVPECL, LVDS, HCSL, CMOS, etc.) and supply voltages (1.5, 1.8, 2.5, or 3.3 V).
• I2C/SMBus-compatible serial interface for programming, supported by ClockBuilder Pro software.

Applications

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

Procurement Notes

Verify the specific ordering suffix B04077 against the manufacturer's official documentation to confirm the exact factory configuration and pinout assignment. Ensure compatibility with I2C bus voltage levels if operating below 2.5 V. Confirm thermal management requirements for the QFN-24 package under maximum load conditions.

Selection Notes

Select this component when designing systems requiring multiple independent clock frequencies from a single IC. Ensure the required output formats (LVPECL, LVDS, etc.) and frequencies are supported by the specific driver configurations. Verify that the input reference source matches the device's supported ranges and that the I2C interface is available for configuration.

Part Context
