SI5338N-B01504-GMR

Overview

The SI5338N-B01504-GMR is a programmable quad clock generator from Skyworks Solutions. It synthesizes four independent output clocks with zero ppm frequency accuracy using MultiSynth technology. The device supports differential and single-ended outputs, including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats. Maximum input frequency reaches 710 MHz via differential inputs, while outputs support up to 710 MHz for LVPECL/LVDS/CML and 200 MHz for CMOS. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, with typical current consumption of 45 mA.

Feature Summary

• MultiSynth technology enables any-frequency synthesis with 0 ppm precision on four independent drivers.
• Supports flexible output formats: LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL.
• Low phase jitter performance, typically 0.7 ps RMS for GbE applications.
• Programmable via I2C/SMBus interface with glitchless frequency and phase adjustment capabilities.

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliant systems
• Ethernet switch/router timing (1 GbE and 10 GbE)
• Processor and FPGA clocking solutions
• Telecom line cards and broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm factory programming parameters. The 'GMR' suffix indicates tape-and-reel packaging. Confirm that the required output frequencies and signal formats align with the device's electrical specifications before procurement.

Selection Notes

Select this component when designing systems requiring multiple independent clock frequencies derived from a single reference. Ensure the target output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) match the load requirements. Verify that the input source matches the supported frequency ranges for differential, single-ended, or crystal inputs.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete crystal oscillators and frequency translators in high-performance digital systems. The device integrates a PLL and four MultiSynth output stages into a compact 4x4 mm QFN package.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineering changes should be validated against the latest Skyworks Solutions data sheet to ensure pinout and electrical compatibility.
