SI5338C-B05601-GM

Overview

The SI5338C-B05601-GM 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 input frequencies up to 710 MHz and generates outputs ranging from 0.16 MHz to 710 MHz depending on the selected format (LVPECL, LVDS, HCSL, CMOS). It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, with typical current consumption of 45 mA. Key electrical parameters include a typical RMS jitter of 0.7 ps and an operating temperature range of -40 °C to +85 °C.

Feature Summary

• MultiSynth technology enables any-frequency synthesis with 0 ppm precision on four independent drivers
• Supports flexible output formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL
• Low phase jitter performance with 0.7 ps RMS typical value
• Programmable via I2C/SMBus interface with glitchless frequency adjustment capabilities

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliant systems
• Ethernet switch and router timing
• Processor and FPGA clocking
• Broadcast video and audio timing

Procurement Notes

Verify the specific factory configuration code associated with the B05601 suffix against the manufacturer's ordering guide to ensure correct frequency and format settings. Confirm package availability and lead times directly with authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when designing systems requiring multiple distinct clock frequencies derived from a single reference source. Ensure the required output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) match the load requirements for each driver. Validate that the input reference signal meets the specified amplitude and slew rate constraints for optimal jitter performance.

Part Context

This part belongs to the Si5338 family of low-jitter clock generators. It serves as a replacement for multiple discrete crystal oscillators in complex digital designs. The 'GM' suffix indicates a lead-free, halogen-free RoHS-compliant QFN-24 package.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other Si5338 variants with different factory configurations. Verify that alternative part numbers support the exact required output frequencies and signal formats before substitution.
