SI5338N-B06157-GMR

Overview

The SI5338N-B06157-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. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, with individual output supplies up to 3.63 V. Maximum input frequency reaches 710 MHz via differential inputs, while maximum output frequencies vary by format, reaching 710 MHz for LVPECL/LVDS/CML. Typical RMS jitter is 0.7 ps.

Feature Summary

• MultiSynth technology enables any-frequency synthesis with 0 ppm precision on four independent outputs.
• Flexible output drivers support LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats.
• Low phase jitter performance with typical RMS values of 0.7 ps.
• 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
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix B06157 against the manufacturer's official documentation to confirm the programmed frequency plan and pinout configuration. Ensure the I2C pull-up voltage complies with register settings if operating below 2.5 V. Confirm package type is 24-QFN (4x4 mm) and temperature range is -40 to +85 °C.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source. Verify that the target output signal formats (LVPECL, LVDS, etc.) match the load requirements. Check that the input reference frequency falls within the supported ranges: 8-30 MHz for crystals, up to 710 MHz for differential inputs. Ensure power supply constraints align with the 1.8/2.5/3.3 V core and variable output supply options.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces multiple discrete crystal oscillators in complex digital systems. The 'N' suffix typically denotes a specific factory-programmed frequency plan, while 'GMR' indicates tape and reel packaging. It is designed for high-performance timing applications requiring low jitter and flexible output configurations.

Replacement Considerations

Direct replacements must be from the Si5338 family with compatible programming. Verify that alternative part numbers support the same output formats and frequency plans. Check for pin-to-pin compatibility in the 24-QFN package. Ensure thermal characteristics and supply voltage ranges match the existing design constraints.
