SI5338F-B04073-GMR

Overview

The SI5338F-B04073-GMR is a programmable quad clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with configurable signal formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates from a 1.8 V, 2.5 V, or 3.3 V core supply with a typical current of 45 mA. Key electrical parameters include a maximum input/output frequency of 710 MHz, a typical phase jitter of 0.7 ps RMS, and an operating temperature range of -40 °C to +85 °C.

Feature Summary

• MultiSynth technology enables independent, glitchless frequency synthesis with 0 ppm accuracy on four outputs.
• Configurable output drivers support multiple voltage levels (1.5V, 1.8V, 2.5V, 3.3V) and signal formats.
• Low phase jitter performance of 0.7 ps RMS typical for high-speed applications.
• I2C/SMBus compatible interface allows flexible configuration via ClockBuilder Pro software.

Applications

• PCIe Gen 1/2/3/4 Common Clock and SRNS compliant systems
• Ethernet switch/router clocking
• Processor and FPGA clock generation
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix B04073 against the manufacturer's latest documentation to confirm pinout assignments and factory programming configurations. Ensure compatibility with I2C bus voltage requirements, as register adjustments may be necessary if the bus voltage is below 2.5 V.

Selection Notes

Select this component when low jitter (<1 ps RMS) and flexible output format configuration are required. Ensure the application supports the 4x4 mm QFN-24 package dimensions and thermal characteristics. Verify that the required output frequencies fall within the supported ranges for the chosen signal format (e.g., up to 710 MHz for LVDS/LVPECL).

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'F' in the model number typically denotes specific pin control features or output enable configurations distinct from other variants like 'B' or 'N'. The '-GMR' suffix indicates tape and reel packaging suitable for automated surface-mount assembly.

Replacement Considerations

Direct replacements within the Si5338 family require verification of the middle alphanumeric code (e.g., B04073) which defines the specific factory-programmed frequency plan and pinout. Generic Si5338 parts may not match the pre-configured settings or hardware pin assignments of the SI5338F-B04073-GMR.
