SI5338N-B05578-GM

Overview

The SI5338N-B05578-GM is a programmable quad clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device accepts inputs from external crystals (8–30 MHz), CMOS (up to 200 MHz), or differential sources up to 710 MHz. 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. Integrated NVM allows for field programming via I2C/SMBus.

Feature Summary

• MultiSynth architecture enables zero ppm precision synthesis across four outputs
• Supports flexible input references including crystal, CMOS, and differential signals up to 710 MHz
• Configurable output drivers support multiple voltage levels (1.5V to 3.3V) and signal formats
• Integrated phase jitter as low as 0.7 ps RMS typ

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 against the manufacturer's latest documentation to confirm factory pre-programming configurations. Ensure compatibility with the intended I2C bus voltage levels, noting that voltages below 2.5 V require specific register writes. Confirm package availability matches the QFN-24 form factor specified in the datasheet.

Selection Notes

Select this component when independent frequency synthesis is required for multiple domains without external oscillators. Validate that the target application fits within the 710 MHz maximum input/output frequency limits. Consider the thermal resistance characteristics if operating at high frequencies with significant load capacitance.
