Modular buffering circuitry for multi-channel transceiver clock and other signals
Circuitry for distributing signals such as reference clock signals among blocks of transceiver circuitry on an integrated circuit such as a field programmable gate array (“FPGA”) employs bidirectional buffers rather than unidirectional buffers. This allows all buffers to have the same construction regardless of physical location, which facilitates construction of the circuitry using identical or substantially identical modules. The same approach may be used for distributing other types of signals among the transceiver blocks. For example, this approach may be used for distributing calibration control signals.
