SI5338C-B04376-GM

Overview

The SI5338C-B04376-GM is a 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 differential and single-ended outputs including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. It operates from a 1.8 V, 2.5 V, or 3.3 V core supply with a typical current of 45 mA. Key electrical parameters include a maximum input frequency of 710 MHz, a maximum output frequency of 710 MHz, and a typical phase jitter of 0.7 ps RMS. It is housed in a 24-lead QFN package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers.
• Supports flexible input references: external crystal (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).
• Highly configurable output drivers supporting up to four differential outputs, eight single-ended outputs, or combinations thereof.
• Independent output voltage per driver selectable at 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 timing.
• Processor and FPGA clocking.
• Broadcast video/audio timing.
• Telecom line cards and MSAN/DSLAM/PON applications.

Procurement Notes

Verify the specific factory programming configuration associated with the B04376 suffix against design requirements. Confirm that the I2C/SMBus interface compatibility matches the system controller. Ensure the operating temperature range of –40 to +85 °C meets environmental specifications. Validate power supply decoupling for the 1.8 V, 2.5 V, or 3.3 V core voltage.

Selection Notes

Select this component when low jitter (0.7 ps RMS typ) and high precision (0 ppm) are required for multiple clock domains. Choose based on the necessary output formats (LVPECL, LVDS, HCSL, etc.) and frequencies (up to 710 MHz). Consider the 4x4 mm QFN package size for space-constrained designs. Verify input reference availability (crystal vs. external clock) to ensure proper configuration.

Part Context

This part belongs to the Si5338 family of I2C-programmable any-frequency, any-output quad clock generators. The 'C' variant typically denotes specific performance characteristics or output configurations within the series. The '-GM' suffix indicates the tape and reel packaging format for surface-mount assembly.

Replacement Considerations

Other Si5338 variants such as SI5338B or SI5338Q may offer different frequency ranges or output configurations. Verify pinout compatibility and electrical specifications before substitution. Consult the official datasheet for detailed ordering information and cross-reference details.
