SI5338A-B01603-GM

Overview

The SI5338A-B01603-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes four independent output clocks with 0 ppm precision, supporting frequencies up to 710 MHz. The device features low phase jitter of 0.7 ps RMS and accepts flexible inputs including differential (up to 710 MHz), single-ended CMOS, and crystal oscillators. Outputs are configurable for LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL formats with independent supply voltages of 1.5, 1.8, 2.5, or 3.3 V. It operates on a single core supply of 1.8, 2.5, or 3.3 V within an industrial temperature range of -40°C to +85°C.

Feature Summary

• MultiSynth technology enables any-frequency synthesis with 0 ppm accuracy on four outputs
• Low phase jitter performance of 0.7 ps RMS typical
• Flexible input support: external crystal (8-30 MHz), CMOS (5-200 MHz), and differential (5-710 MHz)
• Configurable output drivers supporting LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats

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
• Telecom line cards and MSAN/DSLAM/PON equipment

Procurement Notes

Verify the specific B01603 factory configuration against the datasheet's ordering information table to confirm pin assignments and default settings. Confirm package type is 24-QFN (4x4 mm) and check RoHS compliance status. Ensure I2C pull-up voltage requirements match the system design, as register adjustments may be needed for voltages below 2.5 V.

Selection Notes

Select this component when zero ppm frequency accuracy and low jitter are required for multiple independent clock domains. Ensure the target output format (LVPECL, LVDS, etc.) and frequency range fall within the specified limits. Verify that the available input reference source matches one of the supported types, such as differential or single-ended CMOS.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators from Skyworks Solutions. It replaces discrete crystal oscillators by providing synthesized clocks via an I2C interface. The 'B' suffix indicates a specific factory-programmed configuration, while 'GM' denotes the lead-free QFN package.

Replacement Considerations

Direct replacements include other Si5338 variants with different factory configurations (e.g., SI5338A-Bxxxxxx-GM). Ensure the substitute maintains the same 24-QFN footprint and supports the required output formats and frequencies.
