SI5338C-B05960-GM

Overview

The SI5338C-B05960-GM is a programmable quad clock generator utilizing MultiSynth technology to synthesize any frequency with zero ppm precision on four independent outputs. It operates from a single core supply of 1.8, 2.5, or 3.3 V and accepts differential inputs up to 710 MHz. The device features low phase jitter of 0.7 ps RMS typical, glitchless frequency adjustment in 1 ppm steps, and independent phase adjustment with <20 ps resolution. It supports flexible input references including external crystals (8–30 MHz), CMOS, SSTL/HSTL, and differential signals.

Feature Summary

• Four independent output drivers supporting LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats
• Glitchless frequency increment/decrement capability in 1 ppm steps via pin control or I2C
• Independent phase adjustment on each driver with accuracy better than 20 ps
• Configurable spread spectrum generation with modulation rates from 33 to 63 kHz

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and shipping configuration. Ensure the I2C pull-up voltage aligns with the selected core supply voltage to maintain bus compatibility. Confirm that the required output frequencies and signal formats are supported by the specific silicon revision.

Selection Notes

Select this component when zero ppm frequency accuracy and independent output formatting are required. The device supports up to four differential outputs or combinations with single-ended outputs. Ensure the input reference source matches the supported frequency ranges for crystals, CMOS, or differential inputs. Verify thermal dissipation requirements as the typical core supply current is 45 mA.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces multiple discrete crystal oscillators by synthesizing distinct frequencies on a single chip. The device integrates a PLL and MultiSynth stages to provide high-performance jitter attenuation and flexible clock distribution for high-speed digital interfaces.
