Asking for help in understanding "clock and data recovery" with FPGA I've been trying to learn up regarding "clock and data recovery" and how it can work in FPGA. I've read up on a couple of app notes and college lecture slides from Googling, but still have some questions regarding how this is employed in FPGA. Simple Clock & Data Recovery There are two main objectives in receiving data, one is to extract or sync the RTC to the transmitted da ta; in turn this will allow us to sample the received d ata at the correct time. The key to extracting or syncing of the RTC is the use of Murata's Special Start Symbol,

For BPSK signal this is easy, where you can just square your signal, which removes the data. Then you look at the power spectrum, there should be a peak frequency which is called the clock tone, which gives you the symbol period. $\endgroup$ – LWZ Apr 3 '13 at 15:16 Occasionally during data transfer, information is sent without an accompanying clock signal. The corresponding clock signal or frequency must be recovered to make sense of the incoming data. To recover a clock signal from an incoming random data signal, a receiver implements a process called clock-data recovery (CDR).

(Bit 15-13) RXCDR: Receiver Clock/data Recovery. In the TI released PSP, the RXCDR set to 0x04 for 2nd order recovery algorithm. But this setting will cause long lock time in some custom board(I dont know why...) So I modify RXCDR from 0x04 to 0x01 to avoid long lock time...But when I change to 0x01 1st order recovery algorithm.

When you set up disaster recovery for applications, you often need to recover Active Directory and DNS before you recover other application components, to ensure correct application functionality. You can use Site Recovery to create a disaster recovery plan for Active Directory. When a disruption occurs, you can initiate a failover. Another example is the ADN2855, a burst-mode clock and data-recovery IC from Analog Devices which can operate at 155.52 Mbps, 622.08 Mbps, 1244.16 Mbps, or 1250.00 Mbps data rates (selectable via the I 2 C interface).
