                Clock Generation Block (CGB)
 In  Cyclone® 10 GX devices, there are two types of clock generation blocks (CGBs): 
  
 
  - Master CGB
 - Local CGB
 
Transceiver banks with six transceiver channels have two master CGBs. Master CGB1 is located at the top of the transceiver bank and master CGB0 is located at the bottom of the transceiver bank. Transceiver banks with three channels have only one master CGB. The master CGB divides and distributes bonded clocks to a bonded channel group. It also distributes non-bonded clocks to non-bonded channels across the x6/xN clock network.
Each transceiver channel has a local CGB. The local CGB is used for dividing and distributing non-bonded clocks to its own PCS and PMA blocks.
