SI5338C-B06163-GMR

Overview

The SI5338C-B06163-GMR is a programmable quad clock generator from Skyworks Solutions. It synthesizes four independent output clocks with zero ppm frequency accuracy using MultiSynth technology. The device supports differential and single-ended outputs, including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, with individual output drivers configurable for 1.5 V, 1.8 V, 2.5 V, or 3.3 V. Key electrical parameters include a maximum input frequency of 710 MHz, a typical phase jitter of 0.7 ps RMS, and an operating temperature range of -40 °C to +85 °C.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with 0 ppm precision.
• Supports flexible input references: external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).
• Configurable output drivers support various signal formats (LVPECL, LVDS, HCSL, CMOS, SSTL, HSTL) and independent supply voltages.
• Features glitchless frequency adjustments in 1 ppm steps and independent phase adjustment with <20 ps resolution.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the programmed configuration, as the base part number refers to the general device family. Ensure compatibility with I2C/SMBus programming interfaces and check for required software tools like ClockBuilder Pro for configuration.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single package. Verify that the desired output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) match the load requirements. Confirm that the input reference source (crystal, CMOS, or differential) falls within the supported frequency ranges specified in the datasheet.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'C' in the model number typically denotes a specific commercial grade or configuration variant within the Skyworks portfolio. The '-GMR' suffix indicates tape-and-reel packaging for surface-mount assembly.

Replacement Considerations

Direct replacements must be sought from the Si5338 family. Verify pinout compatibility (24-QFN) and electrical specifications. Note that other variants may have different pre-programmed frequencies or output configurations; reprogramming capability should be confirmed if replacing a fixed-configuration unit.

FAQ

What is the maximum input frequency supported by the SI5338?

The maximum input frequency is 710 MHz for differential inputs. Single-ended CMOS inputs support up to 200 MHz, while SSTL/HSTL inputs support up to 350 MHz.

Can the output drivers operate at different supply voltages?

Yes, each of the four output drivers can be independently configured to operate at 1.5 V, 1.8 V, 2.5 V, or 3.3 V, separate from the core supply voltage.

Does the device support glitch-free frequency changes?

Yes, the Si5338 features an independent frequency increment/decrement capability that allows glitchless frequency adjustments in 1 ppm steps.
