SI5338A-B15673-GM

Overview

The SI5338A-B15673-GM is a programmable clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with frequencies up to 710 MHz. The device operates from a 1.8 V, 2.5 V, or 3.3 V core supply and features low phase jitter of 0.7 ps RMS typical. It includes I2C/SMBus programming, spread spectrum capability, and independent glitchless frequency/phase adjustments.

Procurement Notes

Verify the specific factory-programmed NVM content associated with the B15673 suffix against system requirements. Confirm package type and operating temperature range match design specifications before procurement.

Selection Notes

Select this model when independent frequency synthesis on four outputs is required. Ensure input reference frequency falls within supported ranges (5-710 MHz). Verify output voltage levels (1.5V, 1.8V, 2.5V, 3.3V) match load requirements.

Part Context

Part of the Si5338 family of I2C-programmable quad clock generators. Designed to replace multiple crystal oscillators in high-performance digital systems requiring precise clock distribution.

Replacement Considerations

Check compatibility with existing I2C configurations. Verify pinout and package dimensions (QFN-24) are identical for direct replacement.
