SI5338A-B01223-GM

Overview

The SI5338A-B01223-GM is a programmable quad clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. The device accepts flexible inputs such as external crystals (8–30 MHz), CMOS (up to 200 MHz), or differential clocks (up to 710 MHz). Key electrical parameters include a typical phase jitter of 0.7 ps RMS, a core supply voltage range of 1.71 V to 3.63 V, and an operating temperature range of –40 °C to +85 °C.

Feature Summary

• Low power MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers
• High precision synthesis allows true zero ppm frequency accuracy on all outputs
• Independent frequency increment/decrement feature enables glitchless frequency adjustments in 1 ppm steps
• Highly configurable spread spectrum (SSC) on any output with frequencies from 5 to 350 MHz

Applications

• PCIe Gen1/2/3/4 common clock and SRNS
• Ethernet switch/router
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout compatibility and factory configuration. Ensure that the I2C pull-up voltages align with the system requirements, noting that register adjustments may be necessary for bus voltages below 2.5 V.

Selection Notes

Select this component when designing systems requiring multiple independent clock frequencies from a single package. Consider the output driver voltage requirements (1.5 V, 1.8 V, 2.5 V, or 3.3 V) and the input reference type (crystal, CMOS, or differential) during the initial design phase.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'A' designation typically indicates a specific factory programming configuration, while the 'GM' suffix denotes the 24-lead QFN package. Use ClockBuilder Pro software for device configuration.

Replacement Considerations

Direct replacements within the same family include other Si5338 variants with different factory presets. Verify that the substitute part number supports the required output formats and frequencies before implementation.
