SI5338N-B05753-GMR

Overview

The SI5338N-B05753-GMR is a programmable quad clock generator from Skyworks Solutions. It synthesizes four independent output clocks with zero ppm precision 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 up to 710 MHz for differential and 200 MHz for CMOS. Core supply voltage ranges from 1.71 V to 3.63 V, with typical operating current of 45 mA. Integrated phase jitter is typically 0.7 ps RMS.

• Telecom line cards and MSAN/DSLAM/PON equipment

Procurement Notes

Verify the specific ordering suffix B05753 against the manufacturer's official documentation to confirm pre-programmed register settings. Confirm package type is 24-QFN (4x4 mm) and check RoHS compliance status in the latest datasheet revision before procurement.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single IC. Ensure input reference frequency matches available sources (crystal, CMOS, or differential). Verify output voltage levels match target load requirements (1.5V, 1.8V, 2.5V, or 3.3V). Consider thermal resistance of 37 °C/W for PCB layout planning.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete crystal oscillators and frequency translators. The N suffix indicates a specific factory-programmed configuration variant within the broader Si5338 product line.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other Si5338 variants with different factory presets. Cross-family replacement with Si5355/56 requires verification of output driver compatibility and package differences.
