SI5351A-B01975-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5351A-B01975-GTR is a factory preprogrammed I2C-configurable CMOS clock generator from Skyworks Solutions. It features three LVCMOS outputs in a 10-MSOP package, generating frequencies up to 200 MHz with 0 ppm error using an internal oscillator and a 25 or 27 MHz crystal reference. The device operates on a core supply voltage of 2.25 V to 3.6 V and output voltages of 1.8 V, 2.5 V, or 3.3 V. Typical period jitter is less than 70 ps peak-to-peak. It supports spread spectrum modulation, static phase offsets, and glitchless frequency changes.

• Printers, scanners, and projectors

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the B01975 suffix against the target design requirements before procurement. Confirm that the 10-MSOP package dimensions align with the PCB footprint. Ensure the external crystal matches the specified 25 or 27 MHz frequency for proper operation.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a fixed-frequency solution is required without field reprogramming. The Si5351A variant utilizes an internal oscillator, making it suitable for free-running applications. Verify that the required output frequencies fall within the 2.5 kHz to 200 MHz range and that the 10-MSOP package meets space constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5351 family of programmable clock generators. The 'A' designation indicates an internal oscillator version, while the 'Bxxxxx' code signifies a unique factory preprogrammed configuration. The '-GTR' suffix typically denotes tape and reel packaging, though distributor data may vary.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5351A variants with different preprogrammed codes (e.g., SI5351A-Bxxxxx-GT) if the frequency plan differs. For blank configurations, use SI5351A-B-GT. Ensure any substitute maintains the 10-MSOP package and 3-output architecture.
