SI5338A-B04523-GM

Overview

The SI5338A-B04523-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 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 (5–710 MHz).
• Independent output voltage selection per driver: 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. Ensure the I2C pull-up voltage aligns with the system bus requirements, as register configuration may be necessary if the bus voltage is below 2.5 V.

Selection Notes

Select this component when low phase jitter (0.7 ps typ) and high-precision frequency synthesis are required. Confirm that the target application utilizes the supported output formats (LVPECL, LVDS, HCSL, etc.) and that the input reference frequency falls within the specified ranges for the chosen mode.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces multiple discrete crystal oscillators by providing four independently configurable outputs from a single IC, reducing board space and power consumption compared to traditional oscillator arrays.

Replacement Considerations
