SI5334J-B05589-GM

Overview

The SI5334J-B05589-GM is a pin-controlled quad clock generator from Skyworks Solutions. It synthesizes any frequency on four differential outputs using MultiSynth technology, achieving zero ppm frequency error and 0.7 ps RMS typical jitter. The device supports input frequencies up to 710 MHz and output frequencies up to 350 MHz (selectively to 710 MHz). Key features include independent output voltage selection (1.5V to 3.3V), glitchless frequency increment/decrement in 1 ppm steps, and operation across a -40°C to +85°C temperature range within a 24-lead QFN package.

Feature Summary

• MultiSynth Technology: Enables independent, any-frequency synthesis with zero ppm accuracy and low jitter (0.7 ps RMS typ) on four differential outputs.
• Flexible Input/Output: Accepts inputs from 5 to 710 MHz; outputs support LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL formats at voltages of 1.5V, 1.8V, 2.5V, or 3.3V.
• Glitchless Frequency Adjustment: Pin-controlled frequency increment/decrement feature allows adjustments in 1 ppm steps without glitches.
• Low Power & Compact: Operates on 1.8V, 2.5V, or 3.3V core supply with typical current of 45 mA, housed in a space-saving 4x4 mm QFN package.

Applications

• Ethernet switch/router clocking
• PCI Express 2.0/3.0 timing
• Processor and FPGA clock generation
• Telecom line cards and MSAN/DSLAM/PON systems

Procurement Notes

Verify the specific factory-programmed frequency plan associated with the B05589 suffix, as this part number represents a custom configuration rather than a generic programmable unit. Confirm availability through authorized Skyworks distributors, as lead times may vary for pre-programmed silicon.

Selection Notes

Select the SI5334J variant specifically when pin-controlled glitchless frequency increment/decrement functionality is required. Ensure the design accommodates the flexible input requirements (crystal or external clock) and verify that the target output frequencies fall within the supported ranges for the chosen signal format (e.g., LVDS up to 710 MHz, CMOS up to 200 MHz).

Part Context

This component belongs to the Si5334 family of pin-controlled clock generators. The 'J' suffix denotes the specific functional variant featuring frequency increment/decrement capabilities, distinguishing it from variants offering phase adjustment or spread spectrum features. The 'B05589' indicates a unique factory-programmed frequency plan.

Replacement Considerations

Direct replacements must match the Si5334J functional variant for glitchless frequency control. Verify that alternative Skyworks models support the same 24-QFN package and have compatible pinouts for IN1-IN7, CLK0A/B, and power pins.
