3.3. Transmitter Clock Network

The transmitter clock network routes the clock from the transmitter PLL to the transmitter channel. It provides two types of clocks to the transmitter channel:

  • High Speed Serial clock—high-speed clock for the serializer.
  • Low Speed Parallel clock—low-speed clock for the serializer and the PCS.

In a bonded channel configuration, both the serial clock and the parallel clock are routed from the transmitter PLL to the transmitter channel. In a non-bonded channel configuration, only the serial clock is routed to the transmitter channel, and the parallel clock is generated locally within the channel. To support various bonded and non-bonded clocking configurations, four types of transmitter clock network lines are available:

  • x1 clock lines
  • x6 clock lines
  • xN clock lines
