SI5338C-B07590-GM

Overview

The SI5338C-B07590-GM is a programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four independent output drivers with 0 ppm precision. The device supports flexible input references, including external crystals (8–30 MHz), CMOS (up to 200 MHz), and differential inputs (up to 710 MHz). Outputs are configurable for various signal formats such as LVPECL, LVDS, HCSL, and CMOS, with independent 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, features low phase jitter of 0.7 ps RMS typical, and is housed in a 4x4 mm QFN-24 package.

Feature Summary

• I2C/SMBus programmable quad clock generator with 0 ppm frequency accuracy
• Low phase jitter of 0.7 ps RMS typical across all outputs
• Flexible input support: Crystal, CMOS, SSTL/HSTL, and Differential up to 710 MHz
• Independent output configuration for format and voltage (LVPECL/LVDS/CMOS/HCSL)

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards and MSAN/DSLAM/PON

Procurement Notes

Verify the specific factory pre-programmed configuration associated with the B07590 suffix against the target design requirements. Confirm that the I2C address and register settings match the system controller capabilities. Ensure the operating temperature range of -40°C to +85°C aligns with the environmental specifications of the final application.

Selection Notes

Select this component when replacing multiple discrete oscillators with a single low-jitter programmable source. Ensure the required output frequencies fall within the supported ranges for the chosen signal format (e.g., LVDS up to 710 MHz, CMOS up to 200 MHz). Verify that the available input reference matches the device's compatible input types and frequency limits.

Part Context

This part belongs to the Si5338 family of MultiSynth clock generators. The 'C' indicates a specific factory programming configuration, while 'B' denotes the commercial temperature grade (-40 to +85 °C). The 'GM' suffix specifies the 24-lead QFN package and tape-and-reel shipping method. This model replaces fixed-frequency crystal oscillators in high-performance digital systems.
