SI5338A-B01224-GM

Overview

The SI5338A-B01224-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes four independent output clocks with zero ppm frequency accuracy. The device supports differential and single-ended outputs including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. Maximum input frequencies reach 710 MHz for differential inputs. Output frequencies range from 0.16 to 710 MHz depending on the format. Typical phase jitter is 0.7 ps RMS. It operates on a single core supply of 1.8, 2.5, or 3.3 V within an ambient temperature range of -40 to +85 °C.

Feature Summary

• MultiSynth technology enables independent any-frequency synthesis on four drivers with true zero ppm precision.
• Supports flexible input references: external crystals (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), and differential (5-710 MHz).
• Highly configurable output drivers support up to four differential, eight single-ended, or mixed configurations.
• Features glitchless frequency adjustments in 1 ppm steps and independent phase adjustment with <20 ps accuracy.

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 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 current documentation to confirm package type and tape/reel specifications. Confirm that the factory-programmed NVM content matches the required design parameters before integration.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single IC. Ensure the target output voltage levels (1.5, 1.8, 2.5, or 3.3 V) match the load requirements. Verify that the input reference source falls within the supported frequency ranges for the chosen input pin configuration.
