SI5351A-B06165-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5351A-B06165-GT is a factory preprogrammed I2C programmable clock generator in a 10-MSOP package. It provides three LVCMOS outputs with a maximum frequency of 200 MHz and a minimum of 2.5 kHz, utilizing an external crystal reference (25 or 27 MHz). 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 70 ps peak-to-peak, with a maximum duty cycle of 60%. Operating temperature ranges from -40°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming code '06165' against your design requirements, as this suffix determines the exact output frequencies. Confirm that the 10-MSOP package matches your PCB footprint. Ensure the required output voltage levels are supported by the available VDDO options.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a fixed-frequency solution is preferred over user-programmable variants. Verify that the three-output configuration meets system needs, as other packages offer four or eight outputs. Check if the XTAL-only input mode is sufficient, noting that Si5351B/C versions support VCXO or CLKIN inputs.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5351 family of I2C programmable clock generators. The 'A' designation indicates it uses an internal oscillator driven by an external crystal, unlike the 'B' (VCXO) or 'C' (CLKIN) versions. The '-GT' suffix denotes the 10-MSOP package type.

Clock Generators, PLLs, Frequency Synthesizers FAQ

What is the function of the 'A' suffix in the model number?

The 'A' indicates the device version that generates free-running clocks using an internal oscillator driven by an external crystal.

Can the output frequencies be changed after manufacturing?

No, the 'xxxxx' suffix indicates a factory preprogrammed part. To change frequencies, a user-programmable variant like SI5351A-B-GT must be used.

What is the maximum output frequency for this device?

The maximum output frequency is 200 MHz.
