Abstract
Method and apparatus for a bimodal source synchronous interface for a receiver module is described. A first input cell with a first delay chain and a first register block is provided for receipt of a forwarded clock signal by the first delay chain. A second input cell with a second delay chain and a second register block is provided for receipt of a data signal by the second delay chain. The second input cell is configured such that output from the second delay chain is coupled to a data input of the second register block. The first input cell and the second input cell may be operated in either a first modality or a second modality. The first modality may be for interfacing to a synchronous integrated circuit interface. The second modality may be for interfacing to a synchronous network/telecommunications interface.
