SI5338C-B05394-GM

Overview

The SI5338C-B05394-GM 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 differential inputs up to 710 MHz and single-ended CMOS inputs up to 200 MHz. Outputs are configurable for LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats. Key electrical parameters include a core supply voltage of 1.8 V, 2.5 V, or 3.3 V, a typical operating current of 45 mA, and a maximum output frequency of 710 MHz.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with 0 ppm accuracy.
• Low phase jitter performance of 0.7 ps RMS typical value.
• Flexible input reference options: external crystal (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), and differential (5-710 MHz).
• Highly configurable output drivers supporting LVPECL/LVDS/CML (up to 710 MHz), HCSL (up to 250 MHz), CMOS (up to 200 MHz), and SSTL/HSTL (up to 350 MHz).

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 B05394 against the manufacturer's official documentation to confirm the exact factory configuration and programming settings. Ensure compatibility with I2C/SMBus interface requirements and check for moisture sensitivity handling procedures during assembly.

Selection Notes

Select this component when designing systems requiring low-jitter, multi-frequency clock generation from a single IC. Verify that the required output signal formats (LVPECL, LVDS, etc.) and frequencies fall within the specified ranges. Confirm that the system power budget accommodates the typical 45 mA core supply current across the operating temperature range of -40°C to +85°C.
