Title:
SERIALIZER
Document Type and Number:
Japanese Patent JP2009260961
Kind Code:
A
Abstract:
To provide a serializing method which provides sufficient serialization quality at low power even if data rates of serial communication networks become higher.
A first stage configured to convert m-bit-wide parallel data into n-bit-wide parallel data includes a memory unit configured to store the m-bit-wide parallel data 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 is included that is configured to perform conversion into serial data on successive transitions of (n) pieces of phase-shifted versions of the frequency-multiplied derivatives of the timing signal.
