SI5338C-B04190-GMR

Overview

The SI5338C-B04190-GMR is a programmable quad clock generator from Skyworks Solutions. It synthesizes four independent output clocks with zero ppm frequency accuracy using MultiSynth technology. The device supports differential and single-ended outputs, including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats. It operates on 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 any-frequency synthesis with 0 ppm precision on four independent outputs
• Supports flexible output formats: LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL
• Low phase jitter performance of 0.7 ps RMS typical
• Programmable via I2C/SMBus interface with ClockBuilder Pro software support

Applications

• Ethernet switch/router clocking
• PCIe Gen 1/2/3/4 common clock generation
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pinout and configuration settings. Ensure the I2C pull-up voltage matches the system requirements, as register adjustments may be necessary for voltages below 2.5 V. Confirm package availability and moisture sensitivity level handling procedures during assembly.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single IC. Verify that the desired output signal formats (LVDS, LVPECL, etc.) and voltage levels (1.5 V to 3.3 V) are supported by the specific output drivers. Check input reference frequency compatibility, which ranges from external crystals (8-30 MHz) to differential inputs up to 710 MHz.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete crystal oscillators and frequency translators in high-performance digital systems. The device integrates a PLL and four MultiSynth dividers to generate precise clock signals with minimal jitter.
