ABSTRACT:
Circuits and methods convert parallel data into a serial data stream. A serializer according to the present invention generally includes a high speed section and a low speed section. The high speed section generally comprises a tree-based serializer configured to serialize an N-bit parallel data stream, where N is a power of two. The low speed section generally includes a data bank configured to load one or more samples of an M-bit parallel input stream, and a multiplexer configured to produce the N-bit parallel data stream from the data bank. The present invention advantageously provides high speed and relatively low power serialization of M-bit parallel data streams where M is not a power of two. In particular, the present invention advantageously provides high speed and relatively low power serialization of 10-bit parallel data streams.
