  • Patent number: 5805088
    Abstract: A device converts serial data based on one clock to parallel data based on a different, asynchronous clock. The data converter comprises one register bank including first and second registers and another register bank including third and fourth registers. A data input of the first register and a data input of the third register are coupled to receive the serial data. A data input of the second register is coupled to a data output of the first register. A data input of the fourth register is coupled to a data output of the third register. A first clock triggers the first and second registers simultaneously and a second clock triggers the third and fourth registers simultaneously. The first and second clocks alternate with each other. Fifth, sixth, seventh and eighth registers have respective data inputs coupled to respective data outputs of the first, second, third and fourth registers.
