SI5338B-B04162-GM

Overview

The SI5338B-B04162-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes four independent clocks with zero ppm accuracy via an I2C interface. The device supports differential outputs up to 710 MHz and single-ended formats like CMOS (up to 200 MHz) or SSTL/HSTL (up to 350 MHz). Key electrical parameters include a core supply voltage range of 1.71 V to 3.63 V, typical operating current of 45 mA, and a maximum input frequency of 710 MHz. It features low phase jitter of 0.7 ps RMS typ and operates within a temperature range of -40 °C to +85 °C in a 24-lead QFN package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with true zero ppm precision.
• Supports flexible input references including external crystals (8–30 MHz), CMOS (5–200 MHz), and differential inputs (5–710 MHz).
• Highly configurable output drivers support LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats with independent voltage levels.
• Features glitchless frequency adjustments in 1 ppm steps and independent phase adjustment with <20 ps accuracy.

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant timing.
• Ethernet switch/router and 1 GbE/10 GbE applications.
• Processor and FPGA clocking systems.
• Broadcast video/audio timing distribution.
• Telecom line cards and MSAN/DSLAM/PON equipment.

Procurement Notes

Verify the specific factory programming code associated with the B04162 suffix against the manufacturer's ordering information sheet. This suffix indicates a custom configuration stored in non-volatile memory. Confirm that the required pinout and output configurations match the application design before procurement, as these devices are not field-programmable after manufacturing.

Selection Notes

Select this component when designing systems requiring multiple independent clock frequencies from a single source. Ensure the target output format (LVDS, LVPECL, etc.) and frequency requirements fall within the specified limits for the Si5338B variant. Verify that the input reference signal matches one of the supported types, such as a differential clock up to 710 MHz or a single-ended CMOS signal up to 200 MHz.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'B' designation typically denotes a specific factory-programmed configuration variant within the series. The device replaces multiple discrete crystal oscillators, reducing board space and power consumption while providing high-precision timing solutions for complex digital systems.

Replacement Considerations

Direct replacements must be selected from the Si5338 family with identical factory programming codes or equivalent custom configurations. Generic Si5338 parts require reprogramming via ClockBuilder Pro software if the application does not demand the specific pre-configured frequencies of the B04162 variant.
