Notes:
1. Output enable active high
2. On the next negative transition of CLK0 or CLK1.
3. Single-end: Q = low, Q = low
Differential: Q = low, Q = high
2.8. Power Supply (V_DD and V_DDOX)
The device includes separate core (V_DD) and output driver supplies (V_DDOX). This feature allows the core to
operate at a lower voltage than V_DDO, reducing current consumption in mixed supply applications. The core V_DD
supports 3.3 V, 2.5 V, or 1.8 V. Each output bank has its own V_DDOX supply, supporting 3.3 V, 2.5 V, or 1.8 V.
