2.5 Clocking
The clock distribution module is part of the board and shares the CPU PowerPC 405EX and its peripherals
with the Carrier Management Controller functionality. In addition the clock distribution module has its own
features which are the PCIe Clock distribution and the Telco Clock Distribution.
2.5.1 PCIe Clock Distribution
• 100MHz PCIe GEN2 generator with SSC support
• 100MHz HCS GEN2 clock signal to tongue 3
• 100MHz HCS clock signal to local device (optional)
• CLK3-[12:1]_P/N HCS outputs to AMC[12:1]
2.5.2 Telco Clock Distribution
• CLK1-[12:1]_M-LVDS input/outputs to/from AMCs
• CLK2-[12:1]_M-LVDS inputs/outputs to/from AMCs
• CLK1_RX_M-LVDS input from other MCH
• CLK1_TX_M-LVDS output to other MCH
• CLK3_RX_M-LVDS input from other MCH
• CLK3_TX_M-LVDS output to other MCH
