Finding Si5351 Component
Thought for 1 min 43 sec
Here’s a pinout verification of the SI5351A-B-GT MSOP-10 symbol in this project against the datasheet PDF (Table 13 “Si5351A 10‑MSOP Pin Descriptions”). All power, I2C, and clock pins match.
SI5351A-B-GT MSOP-10: symbol vs datasheet
Table
| Symbol pin | Symbol no. | Symbol type | Datasheet no. | Datasheet function | Match |
|---|---|---|---|---|---|
| VDD | 1 | powerIn | 1 | Core voltage supply | Yes |
| VDDO | 7 | powerIn | 7 | Output supply for CLK0/1/2 | Yes |
| GND | 8 | powerIn | 8 | Ground | Yes |
| SCL | 4 | input | 4 | I2C serial clock (requires pull-up) | Yes |
| SDA | 5 | bidi | 5 | I2C serial data (requires pull-up) | Yes |
| CLK0 | 10 | output | 10 | Output clock 0 | Yes |
| CLK1 | 9 | output | 9 | Output clock 1 | Yes |
| CLK2 | 6 | output | 6 | Output clock 2 | Yes |
Notes
- Datasheet states SCL is input and SDA is I/O and that both “must be pulled up using a pull-up resistor of at least 1 kΩ.” Verify your I2C bus design values separately.
- Crystal pins XA=2 and XB=3 also align with the datasheet, though not listed above since you asked for power, I2C, and clock pins.
If you want, I can also check the footprint/package mapping for the MSOP-10 pin 1 orientation and pad count.
