Notes:
1. Permanent device damage may occur if the absolute maximum ratings are exceeded. Functional operation should be
restricted to the conditions as specified in the operational sections of this data sheet. Exposure beyond recommended
operating conditions for extended periods may affect device reliability.
2. The Si4312 device is a high-performance RF integrated circuit with certain pins having an ESD rating of < 2 kV HBM.
Handling and assembly of this device should only be done at ESD-protected workstations.
3. For input pins 315/434, RATIO, BT[1:0], TH[1:0].
4. At RF input pin RX_IN.
