SI5338N-B05316-GM

Overview

The SI5338N-B05316-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, HCSL, CMOS, SSTL, and HSTL. The device operates from a 1.8 V, 2.5 V, or 3.3 V core supply with a typical current of 45 mA. It accepts inputs up to 710 MHz via differential pins or 200 MHz via single-ended pins. Key electrical parameters include a maximum output frequency of 710 MHz, a typical phase jitter of 0.7 ps RMS, and operation within a temperature range of -40 °C to +85 °C.

Feature Summary

• MultiSynth™ technology enables zero ppm precision synthesis on four independent outputs.
• Flexible input support: external crystals (8-30 MHz), CMOS (up to 200 MHz), and differential (up to 710 MHz).
• Configurable output drivers supporting LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats.
• Independent output voltage selection per driver: 1.5 V, 1.8 V, 2.5 V, or 3.3 V.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm factory programming configurations. Ensure I2C pull-up voltages are compatible with the selected VDDI2C level, as register adjustments may be required for voltages below 2.5 V.

Selection Notes

Select this component when low jitter (< 1 ps RMS) and flexible output format compatibility are required. Confirm that the desired output frequencies do not exceed the limits defined by the Fvco divider ratios (Fvco/4 and Fvco/6) for frequencies above 350 MHz.

Part Context

This part belongs to the Si5338 family of high-performance clock generators. It replaces multiple discrete crystal oscillators in complex digital systems. The 'N' suffix typically denotes specific factory-programmed settings, while 'GM' indicates the QFN-24 package and tape-and-reel shipping method.

Replacement Considerations

Compatible replacements within the same family include SI5338C, SI5338Q, and SI5338K variants. Verify pinout compatibility and ensure the substitute part supports the required output formats and frequencies specified in the design.
