SI5338A-B05147-GMR

Overview

The SI5338A-B05147-GMR is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes four independent output clocks with zero ppm frequency accuracy and low jitter (0.7 ps RMS typical). The device supports flexible input references, including differential inputs up to 710 MHz, and offers configurable output formats such as LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. Powered by a single core supply of 1.8 V, 2.5 V, or 3.3 V, it operates within a temperature range of -40 °C to +85 °C in a 24-lead QFN package.

Feature Summary

• MultiSynth technology enables any-frequency synthesis on four outputs with 0 ppm precision
• Low phase jitter of 0.7 ps RMS typical for high-performance timing applications
• Flexible input support: external crystal (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential (5–710 MHz)
• Independent output voltage selection per driver: 1.5 V, 1.8 V, 2.5 V, or 3.3 V

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliant systems
• Ethernet switch/router and 1 GbE/10 GbE interfaces
• Processor and FPGA clocking solutions
• Broadcast video/audio timing infrastructure

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status through official datasheets prior to procurement. Ensure I2C pull-up voltages align with the selected bus voltage requirements for proper interface operation.

Selection Notes

Select this component when independent frequency synthesis across four channels is required without integer multiples constraints. Verify that the target output frequencies fall within the supported ranges for the chosen signal format (e.g., LVPECL/LVDS up to 710 MHz). Ensure the application environment stays within the specified -40 °C to +85 °C operating temperature range.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators from Skyworks Solutions. The family utilizes patented MultiSynth architecture to replace multiple discrete oscillators. The 'A' designation typically indicates performance grade variations within the series, while the suffix defines packaging and configuration details.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other Si5338 variants with different frequency grades or output configurations. Verify electrical parameters such as maximum output frequency and jitter specifications before substituting with other SKUs like SI5338B or SI5338Q.
