SI5338A-B06137-GM

Overview

The SI5338A-B06137-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes four independent output clocks with zero ppm frequency accuracy. The device supports differential and single-ended outputs including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats. Maximum output frequencies reach 710 MHz for differential signals 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. Jitter performance is specified at 0.7 ps RMS typ.

Feature Summary

• MultiSynth technology enables independent any-frequency synthesis on four output drivers
• Supports flexible input references: external crystal (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), and differential inputs (5-710 MHz)
• Independent output voltage per driver selectable from 1.5, 1.8, 2.5, or 3.3 V
• Glitchless frequency adjustments in 1 ppm steps via independent increment/decrement feature

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant systems
• Ethernet switch/router and 1 GbE/10 GbE interfaces
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards and Fibre Channel/SAN applications

Procurement Notes

Verify the specific factory programming code 'B06137' against the official Skyworks ordering guide to confirm the exact synthesized frequencies and output configurations. Ensure I2C pull-up voltages are compatible with the selected VDDI2C range, noting that register 27 must be written if the bus voltage is below 2.5 V.

Selection Notes

Select this component when replacing multiple discrete oscillators with a single low-jitter source. Confirm that the required output signal formats (LVPECL, LVDS, etc.) match the configurable drivers. Verify that the input reference frequency falls within the supported ranges for the chosen input pin type.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The suffix 'GM' indicates a 24-lead QFN package. The 'B' designation typically refers to the revision level associated with lead frame modifications as documented in Skyworks Product Change Notifications.

Replacement Considerations

Direct replacements include other Si5338 variants such as SI5338A-B-GM or SI5338Q-B-GMR, provided the specific frequency plan programmed into the NVM matches the application requirements.
