SI5338M-B05701-GMR

Overview

The SI5338M-B05701-GMR is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology for independent frequency synthesis on four output drivers. It supports differential and single-ended outputs with frequencies up to 710 MHz. The device features low phase jitter of 0.7 ps RMS typical, zero ppm frequency accuracy, and glitchless frequency adjustments. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V and is housed in a compact 4 x 4 mm QFN-24 package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with 0 ppm precision.
• Low phase jitter of 0.7 ps RMS typical across LVDS, LVPECL, HCSL, and CML formats.
• Flexible input reference options including external crystals (8–30 MHz), CMOS (5–200 MHz), and differential inputs (up to 710 MHz).
• Independent output voltage configuration per driver at 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 solutions.
• Processor and FPGA clocking architectures.
• Broadcast video/audio timing distribution.
• Telecom line cards and MSAN/DSLAM/PON equipment.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout compatibility and factory programming settings. Ensure I2C pull-up voltages align with the selected bus standard requirements. Confirm thermal management strategies for the QFN-24 package under maximum load conditions.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single source. Verify that the desired output signal formats (LVDS, LVPECL, etc.) match the target receiver specifications. Check input frequency ranges against available reference clocks to ensure valid PLL lock conditions.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete crystal oscillators and frequency translators. The device integrates a phase-locked loop and multiple MultiSynth dividers to generate precise clock signals without external resonators.

Replacement Considerations

Direct replacements within the Si5338 series include SI5338A, SI5338B, SI5338F, SI5338K, SI5338M, SI5338N, and SI5338Q variants. Verify that the substitute part number matches the required output frequency range and jitter specifications for the specific application design.
