Samsung patents glitch filter for high-speed data transmitters
Samsung has been granted a patent for a system that improves the reliability of SerDes transmitters, which are used to send data quickly between chips. The invention uses a specific timing delay to synchronize a signal that filters out small errors, or glitches, before the data is sent.
In the filing’s own words
There is provided a system and a method for filtering out glitches in a SerDes transmitter. The SerDes transmitter includes a latency generation block, and a 2-to-1 serializer. The latency generation block is configured to synchronize a feed forward equalization (FFE) enable signal to a half rate domain by creating a latency in the FFE enable signal, and provide the synchronized FFE enable signal to a plurality of synchronized FFE selection multiplexers. The SerDes transmitter further includes a 2-to-1 serializer that is configured to filter out a glitch using the synchronized FFE enable signal in the half rate domain.
What exactly they claim (claim 1)
1. A serializer/deserializer (SerDes) transmitter comprising: a latency generation circuit configured to: synchronize a feed forward equalization (FFE) enable signal to a half rate domain based on a latency in the FFE enable signal, the latency being equal to a latency in a first serializer configured to serialize input data; and provide the synchronized FFE enable signal in the half rate domain to a plurality of synchronized FFE selection multiplexers (MUXes); and a 2-to-1 serializer circuit configured to filter out a glitch using the synchronized FFE enable signal in the half rate domain in the plurality of synchronized FFE selection MUXes based on the synchronized FFE enable signal.
