Abstract
A serializer includes a first stage configured to convert m-bit-wide parallel data into n-bit-wide parallel data, where n is 2, m≧2, x is an integer of at least 1, and y is an integer of at least 1, where the first stage includes a memory unit configured to store the m-bit-wide parallel in response to a timing signal and a first multiplexer configured to output the n-bit-wide parallel data in response to a frequency-multiplied derivative of the timing signal, and a current mode logic (CML) multiplexer stage configured to convert the n-bit-wide parallel data into serial data on successive transitions of n phase-shifted versions of the frequency-multiplied derivative of the timing signal.
