SI5338N-B05007-GM

Overview

The SI5338N-B05007-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 pairs or 200 MHz via single-ended pins. Key electrical parameters include a maximum input frequency of 710 MHz, a maximum output frequency of 710 MHz for differential outputs, and a typical RMS jitter of 0.7 ps.

Feature Summary

• MultiSynth™ technology enables zero ppm precision synthesis on four independent outputs.
• Supports flexible input references: external crystals (8–30 MHz), CMOS (5–200 MHz), and differential signals (up to 710 MHz).
• Configurable output drivers support LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats.
• Features glitchless frequency adjustment 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 systems.
• Ethernet switch/router and 1 GbE/10 GbE interfaces.
• Processor and FPGA clocking solutions.
• Telecom line cards and MSAN/DSLAM/PON equipment.

Procurement Notes

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

Selection Notes

Select this component when low jitter (<1 ps RMS) and high flexibility in output formats are required. Confirm that the application requires independent voltage levels for output drivers, as each driver supports 1.5 V, 1.8 V, 2.5 V, or 3.3 V. Validate that the input reference frequency falls within the supported ranges for the chosen input pin configuration.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces multiple discrete crystal oscillators by providing four independent clock outputs from a single reference source. The device integrates an internal PLL and NVM for storing configuration data, reducing board space and power consumption compared to discrete oscillator arrays.
