SI5338N-B06152-GM

Overview

The SI5338N-B06152-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency up to 710 MHz with zero ppm accuracy on four independent outputs. The device supports LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats. Key electrical parameters include a core supply voltage of 1.8 V, 2.5 V, or 3.3 V, a typical operating current of 45 mA, and a typical RMS phase jitter of 0.7 ps. It operates within an ambient temperature range of -40 °C to +85 °C.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers.
• Supports flexible input references including external crystals (8-30 MHz), CMOS (5-200 MHz), and differential inputs (up to 710 MHz).
• Features glitchless frequency adjustments in 1 ppm steps and independent phase adjustment with <20 ps accuracy.
• Configurable spread spectrum modulation with frequencies from 5 to 350 MHz and spreads from 0.5% to 5.0%.

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 applications.

Procurement Notes

Verify the specific factory-programmed NVM configuration associated with the B06152 suffix against the system requirements. Confirm that the QFN-24 package dimensions and thermal characteristics meet the PCB layout constraints. Ensure I2C pull-up voltages are compatible with the selected core supply voltage.

Selection Notes

Select this component when independent frequency synthesis for multiple domains is required without external oscillators. Verify that the target output formats (LVPECL, LVDS, etc.) match the load requirements. Check if the 0.7 ps RMS jitter specification meets the sensitivity of the downstream receivers. Consider the 45 mA typical current draw for power budget calculations.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'N' designation typically indicates a custom factory-programmed variant with specific frequencies stored in non-volatile memory. The 'GM' suffix denotes the 24-lead QFN package. It replaces discrete crystal oscillators and buffer chains in complex digital systems.

Replacement Considerations

Direct pin-to-pin replacements within the same family require identical NVM programming. Generic Si5338 variants may differ in default output configurations or supported frequency ranges. Validate that substitute parts support the required output formats and jitter performance specifications.
