SI5338C-B05601-GMR

Overview

The SI5338C-B05601-GMR is a programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. The device supports flexible input references, including external crystals (8–30 MHz), CMOS (up to 200 MHz), and differential inputs (up to 710 MHz). Outputs are configurable for LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL formats, with individual supply voltages of 1.5, 1.8, 2.5, or 3.3 V. It operates on a single core supply (1.8, 2.5, or 3.3 V) within a 4x4 mm QFN-24 package.

Feature Summary

• Four independent output drivers capable of synthesizing any frequency up to 710 MHz with 0 ppm accuracy.
• Low phase jitter performance of 0.7 ps RMS typical.
• Supports glitchless frequency adjustments in 1 ppm steps via independent increment/decrement features.
• Configurable spread spectrum generation with modulation rates from 33 to 63 kHz.

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 factory programming configuration associated with the B05601 suffix against the system requirements. Confirm that the I2C/SMBus interface voltage levels match the host controller logic. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS inputs and outputs.

Selection Notes

Select this component when replacing multiple discrete oscillators with a single low-jitter source. Verify that the required output signal formats (LVPECL, LVDS, etc.) and frequencies fall within the specified ranges. Check that the available input reference frequency matches the supported ranges for crystal or digital inputs.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'C' indicates the commercial temperature range (-40°C to +85°C). The 'B' denotes a specific factory-programmed configuration. The 'GMR' suffix indicates tape and reel packaging for surface-mount assembly.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other Si5338 variants with different factory configurations. Ensure the substitute part supports the required output frequencies and formats. Verify compatibility with existing I2C programming software if field reconfiguration is needed.
