DESCRIPTION each SD10 interface SD10 transceiver. transceiver contains transmitter block receiver block. transmitter accepts 10-bit wide 8b10b encoded data parallel inputs serializes this data 1-bit wide 3.2Gb/s signal. transmitter driver outputs this signal differential signal over wires. data rate input wires 320Mb/s wire, line with clock rates easily achievable core area ASICs. receiver receiver buffer accepts differential signal recovers timing information. deserializer generates 10-bit wide logic signal, together with aligned clock. Options HSPI compatibility coding. Standard comma detection included. SD10 transceiver requires reference clock signal. transmitter includes pre-emphasis receiver includes equalization extend transmission over longer copper wires. data rates this description examples. Other data rates possible. BLOCK DIAGRAM Shown block diagrams SD10 full-duplex interface SD10 transceiver macro.
