SI5338N-B06152-GMR

Overview

The SI5338N-B06152-GMR is an I2C-programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four output drivers with zero ppm precision. The device supports differential and single-ended outputs, including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats. It operates with a core supply voltage of 1.8 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. Input references include external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers.
• Low phase jitter of 0.7 ps RMS typical for high-performance timing applications.
• Highly configurable output drivers supporting up to four differential or eight single-ended outputs.
• I2C/SMBus compatible interface for easy programming via ClockBuilder Pro software.

Applications

• PCIe Gen 1/2/3/4 common clock and 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 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 the I2C bus voltage levels are compatible with the selected core supply voltage.

Selection Notes

Select this component when independent frequency synthesis on multiple outputs is required without external oscillators. Consider the output format compatibility (LVPECL, LVDS, etc.) and voltage levels (1.5 V to 3.3 V) for each driver. Evaluate the input reference type (crystal vs. external clock) to ensure proper pin usage and circuit design.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'N' indicates a specific performance grade or variant within the series, while the 'B06152' suffix denotes a unique factory-programmed configuration stored in non-volatile memory. The '-GMR' suffix indicates tape and reel packaging for surface-mount assembly.

Replacement Considerations

Direct replacements must match the Si5338 family specifications and the specific B06152 configuration. Verify that alternative parts support the same output formats, frequencies, and jitter performance. Check for pin-to-pin compatibility if substituting in an existing design.
