Abstract
In certain embodiments of the invention, a serializer has a transfer stage that transfers N-bit parallel data from a relatively slow timing domain to a relatively fast timing domain and a serializing stage that converts the parallel data into serialized data. Between the transfer stage and the serializing stage is an update stage that buffers the data and can be used to toggle the serializer between an N−1 operating mode and an N+1 operating mode.
