2.2. SERDES Blocks, Modes, and Clock Domains

Figure 2. SERDES CircuitryThis figure shows a transmitter and receiver block diagram for the SERDES circuitry with the interface signals of the transmitter and receiver data paths. The figure shows a transmitter and a receiver sharing an I/O PLL as they are in the same sub-bank and using the same I/O PLL resource. In single data rate (SDR) and double data rate (DDR) modes, the data widths are 1 and 2 bits, respectively.
