1.3.1. Transceiver Bank Architecture
Each L-Tile/H-tile transceiver tile contains four transceiver banks. The transceiver channels are grouped into transceiver banks, where each bank has six channels. These six channels are a combination of GX and GXT channels which you can configure in the following ways:
- All six channels as GX channels
- Channels 0, 1, 3, and 4 as GXT channels. L-Tile supports GXT channels in banks 1 and 3. H-Tile supports GXT channels in banks 0, 1, 2, and 3.
- All six channels as a mix of GX and GXT channels; for example, two GX channels and four GXT channels on H-Tile Devices. On L-Tile devices, you can use a maximum of four channels in a bank when any channel is configured as a GXT channel.
Each channel can also run in any of the following operational modes:
- Duplex (default)—Specifies a single channel that supports both transmission and reception
- Transmitter (TX) Simplex—Specifies a single channel that supports only transmission
- Receiver (RX) Simplex—Specifies a single channel that supports only reception
Each transceiver bank contains two Advanced Transmit (ATX) PLLs, two fractional PLLs (fPLL), and two Clock Multiplier Unit (CMU) PLLs.
