SI5338N-B05167-GM

Overview

The SI5338N-B05167-GM 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. Maximum input frequency reaches 710 MHz via differential inputs, while outputs support frequencies up to 710 MHz for differential and 200 MHz for CMOS. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, with typical current consumption of 45 mA. Jitter performance is specified at 0.7 ps RMS typ.

Feature Summary

• MultiSynth technology enables any-frequency synthesis with 0 ppm precision on four independent drivers.
• Flexible output configurations supporting LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL signal formats.
• Low phase jitter of 0.7 ps RMS typical, compliant with PCIe Gen 1/2/3/4 common clock standards.
• I2C/SMBus compatible interface for programming, supported by ClockBuilder Pro software.

Applications

• PCIe Gen 1/2/3/4 systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet revision 1.6 to confirm pinout and electrical characteristics. Ensure I2C pull-up voltages are within the 1.71 V to 3.63 V range and register settings are adjusted if the bus voltage is below 2.5 V. Confirm thermal management requirements for the QFN-24 package in the target application environment.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single source. Verify that the desired output signal format (LVPECL, LVDS, etc.) matches the load requirements. Check that the input reference frequency falls within the supported ranges: 8–30 MHz for crystals, up to 710 MHz for differential inputs. Ensure the operating temperature range of –40 °C to +85 °C meets system specifications.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete crystal oscillators and frequency translators. The device integrates a PLL and four MultiSynth dividers to generate precise clock signals. It is designed for high-performance digital systems requiring low jitter and flexible clock distribution.

Replacement Considerations

Direct replacements within the Si5338 family include SI5338Q-B-GMR and SI5338C-B01039-GM. Verify compatibility of the I2C address and register map. Ensure the replacement part supports the required output formats and maximum frequencies for the specific design application.
