SI5338C-B05611-GMR

Overview

The SI5338C-B05611-GMR is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with configurable voltage levels (1.5V, 1.8V, 2.5V, or 3.3V). The device operates from a single core supply of 1.8V, 2.5V, or 3.3V, drawing a typical current of 45 mA. It features low phase jitter of 0.7 ps RMS typ, flexible input references up to 710 MHz, and I2C/SMBus programming via ClockBuilder Pro software.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with 0 ppm precision.
• Supports diverse output formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL with independent voltage selection per driver.
• Low phase jitter performance of 0.7 ps RMS typical, compliant with PCIe Gen 1/2/3/4 common clock standards.
• Flexible input reference options: external crystal (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), or differential (5-710 MHz).

Applications

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

Procurement Notes

Verify the specific factory configuration encoded in the ordering suffix B05611 against design requirements using ClockBuilder Pro software. Confirm package type is 24-QFN (4x4 mm) and operating temperature range is -40°C to +85°C. Ensure I2C pull-up voltages match the selected VDDI2C level for proper communication.

Selection Notes

Select this component when replacing multiple discrete oscillators with a single programmable source. Ensure the required output frequencies fall within the supported ranges (up to 710 MHz for differential, 200 MHz for CMOS). Verify that the target application can accommodate the 45 mA typical core supply current and the 4x4 mm QFN footprint.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'C' indicates commercial temperature grade (-40 to +85 °C), while 'B' denotes a specific factory pre-programmed configuration. The '-GMR' suffix signifies 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 (e.g., SI5338C-Bxxxxx-GMR). Ensure the replacement part's pre-programmed settings match the original design or reprogram the new device using ClockBuilder Pro.
