SI5338C-B05720-GM

Overview

The SI5338C-B05720-GM 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 formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates with a core supply of 1.8 V, 2.5 V, or 3.3 V and accepts inputs up to 710 MHz. Key electrical parameters include a typical RMS jitter of 0.7 ps, a maximum output frequency of 710 MHz for differential outputs, and an operating temperature range of -40 °C to +85 °C.

Feature Summary

• MultiSynth™ technology enables zero ppm precision frequency synthesis on four independent outputs.
• Supports flexible input references: external crystals (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), and differential inputs (5-710 MHz).
• Independent output voltage configuration per driver at 1.5 V, 1.8 V, 2.5 V, or 3.3 V.
• Glitchless frequency adjustments via independent increment/decrement features in 1 ppm steps.

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant systems.
• Ethernet switch/router and 1 GbE/10 GbE interfaces.
• Processor and FPGA clocking solutions.
• Broadcast video/audio timing infrastructure.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout compatibility and factory programming settings. Confirm that the I2C pull-up voltage requirements align with the system bus voltage, particularly if operating below 2.5 V.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single package. Ensure the target output format (LVDS, LVPECL, etc.) matches the receiver specifications. Validate that the input reference source meets the slew rate requirements for optimal jitter performance.

Part Context
