SI5338M-B04505-GM

Overview

The SI5338M-B04505-GM is a programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four output drivers with zero ppm precision. The device supports differential and single-ended outputs, including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats. It operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. Configuration is performed via an I2C/SMBus interface.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers
• Low phase jitter of 0.7 ps RMS typical
• Flexible input reference supporting external crystals (8-30 MHz), CMOS, SSTL/HSTL, and differential inputs up to 710 MHz
• Independent output voltage per driver: 1.5, 1.8, 2.5, or 3.3 V

Applications

• Ethernet switch/router
• PCIe Gen1/2/3/4
• Processor and FPGA clocking
• Telecom line cards
• Fibre Channel, SAN

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout configuration and factory programming settings. Ensure compatibility with the required I2C bus voltage levels for system integration.

Selection Notes

Select this component when designing systems requiring multiple independent clock frequencies derived from a single source. Verify that the required output signal formats (LVPECL, LVDS, etc.) and frequencies are supported by the specific output driver configurations available in the datasheet.
