SI5338M-B10094-GMR

Overview

The SI5338M-B10094-GMR is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with configurable voltage levels (1.5V, 1.8V, 2.5V, or 3.3V). The device operates on a single core supply of 1.8V, 2.5V, or 3.3V, drawing a typical current of 45 mA. It features low phase jitter of 0.7 ps RMS typ, glitchless frequency adjustments in 1 ppm steps, and independent phase adjustment with <20 ps accuracy. The component is housed in a 4x4 mm QFN-24 package.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four differential output drivers with 0 ppm precision.
• Supports flexible input references including external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).
• Highly-configurable output drivers supporting LVPECL/LVDS (up to 710 MHz), HCSL (up to 250 MHz), CMOS (up to 200 MHz), and SSTL/HSTL (up to 350 MHz).
• Features independent frequency increment/decrement for glitchless adjustments in 1 ppm steps and independent phase adjustment with <20 ps step accuracy.

Applications

• PCIe Gen1/2/3/4 Common Clock and Gen 3 SRNS compliant systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards and MSAN/DSLAM/PON

Procurement Notes

Verify the specific ordering suffix 'M' against the manufacturer's latest documentation to confirm pinout configuration and factory programming details. Ensure compatibility with I2C/SMBus interface requirements and check for moisture sensitivity handling procedures during assembly.

Selection Notes

Select this model for applications requiring independent frequency synthesis on four outputs with low jitter performance. Consider the supported output formats (LVPECL, LVDS, HCSL, CMOS, etc.) and voltage levels to match load requirements. Verify that the input reference frequency range aligns with available system clocks.
