SI5338D-B04193-GM

Overview

The SI5338D-B04193-GM is an I2C-programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. The device supports a wide range of input references, including external crystals (8–30 MHz), CMOS (up to 200 MHz), and differential inputs (up to 710 MHz). Outputs are configurable for LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL formats, with individual supply voltages of 1.5, 1.8, 2.5, or 3.3 V per driver. It operates on a single core supply of 1.8, 2.5, or 3.3 V within a 4x4 mm QFN-24 package.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with 0 ppm accuracy.
• Low phase jitter performance of 0.7 ps RMS typical.
• Flexible input support: External crystal (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and Differential (5–710 MHz).
• Independent output voltage configuration per driver: 1.5, 1.8, 2.5, or 3.3 V.

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant systems.
• Ethernet switch/router and 1 GbE/10 GbE timing.
• Processor and FPGA clocking.
• Broadcast video/audio timing.
• Telecom line cards and Fibre Channel/SAN applications.

Procurement Notes

Verify the specific ordering suffix B04193 against the manufacturer's current documentation to confirm factory programming parameters. Ensure the I2C pull-up voltage requirements align with the system bus voltage, particularly if operating below 2.5 V. Confirm RoHS compliance status via the official datasheet before procurement.

Selection Notes

Select this component when low jitter (< 1 ps RMS) and flexible output format mixing are required. Ensure the input reference frequency falls within the supported ranges for the chosen mode. Verify that the target application requires independent output voltage levels, as this feature distinguishes it from fixed-voltage alternatives.
