Clocks
There is a quad clock synthesizer (
Si5338B) with the following outputs programmed:
- clk0 is programmed as 156.25 for T1 with 10Gbit Ethernet SFPs
- clk1 feeding both T1 and T2 is programmed as 125.00, SFPs on T1 with DAQLSC is also fed by this clock (this includes both the 5.0Gb/s and 10.0Gb/s fiber DAQ output modes)
- clk2 feeding AMC link is programmed as 250.00 (backplane link from AMC cards on Fabric A)
- clk3 feeding DDR memory is programmed as 200.00 for new T1 and 225.00 for old T1
