SI5338A-B04406-GMR

Overview

The SI5338A-B04406-GMR 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, CML, HCSL, CMOS, SSTL, and HSTL formats. Maximum output frequencies reach 710 MHz for differential signals and 200 MHz for CMOS. 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. Jitter performance is specified at 0.7 ps RMS typ. Configuration is managed via an I²C/SMBus interface.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with true zero ppm accuracy.
• Low phase jitter of 0.7 ps RMS typ, compliant with PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS standards.
• Highly configurable output drivers supporting up to four differential outputs, eight single-ended outputs, or mixed configurations.
• Flexible input reference options including external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).

Applications

• PCIe Gen 1/2/3/4 systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards

Procurement Notes
