Scalable receiver architecture for silicon photonic links

An apparatus comprising:

• sampling circuitry, coupled to photodetector circuitry, to generate a first sampled signal based on an analog signal;
• data slicer circuitry, coupled to the sampling circuitry, to generate a first data signal and a first error signal each based on the first sampled signal, wherein the first data signal comprises first symbols according to a first alphabet;
• decoder circuitry, coupled to the data slicer circuitry, to generate a second data signal based on the first data signal and a decoder function;
• and
• modulo circuitry, coupled to the decoder circuitry, to perform modulo operations, based on the first symbols and to generate second symbols of the second data signal, wherein the second symbols are according to a second alphabet, wherein the first alphabet comprises a first number of symbols and the second alphabet comprises a second number of symbols, and the second number is one less than the first number.

A system comprising:

• a processor and a memory to execute an operating system;
• a control hub coupled to the processor;
• a display device coupled to the control hub, the display device to display an image based on a display signal communicated to the display device;
• and
• a transceiver coupled to the control hub, the transceiver comprising:
• sampling circuitry to generate a sample analog signal, and equalization circuitry, coupled to sampling circuitry, the equalization circuitry comprising a plurality of memory elements to store sample analog signals, each having a tap, to generate an equalized signal based on the sample analog signal, the equalized signal comprising first and second sample values corresponding with a cursor tap and a first postcursor tap, and a plurality of third sample values corresponding with taps other than the cursor tap and the first postcursor tap, wherein a first amplitude of the first sample value and a second amplitude of the second sample value are substantially equal, and amplitudes of the plurality of third sample values are attenuated relative to the first and second sample values.
