A first serializing stage is provided with a stream of data words composed of sub-words that each have values that associate each of the sub-words with the same error detection code value. For example, the values selected for each sub-word may each be associated with even parity. One or more serializing stages time-multiplex the sub-words into a stream of sub-word sized data. At the serializing stage that receives sub-word sized data stream, the data is checked to determine whether any of the sub-words is no longer associated with the error detection code value. Serializing/deserializing stages are selectively controlled to replace one or more data bits from a word being serialized/deserialized with an error detecting code value (e.g., parity). A subsequent serializing/deserializing stage is enabled to use the inserted error detecting code values and the data in the received words to determine whether an error has occurred.

Serializing and deserializing stage testing

A high speed transmit driver is provided, along with methods to improve driver slew rate, decrease transmit jitter, improve termination accuracy, and decrease sensitivity to supply noise.

High-speed SSR transmit driver

Various devices, circuits and systems including filter sections for creating complex poles are described herein. For example, various circuits including transistors, tuning capacitors and resistors are described. In the circuits, the tuning capacitor is electrically coupled between the gate and source of the transistor, and the resistor is electrically coupled to the gate of the transistor. In one configuration, the circuit input is applied to the gate of the transistor via the resistor, and the output is taken from the source of the transistor. In another configuration, the input is applied to the source of the transistor, and the output is taken from the same source. In yet another configuration, the input is applied at the source of the transistor and the output is taken from the drain of the transistor.
