Abstract: A serializer and de-serializer circuit which is particularly well-suited for use in communicating digital data from one integrated circuit (chip) to another for implementing chip-to-chip communications is presented. The circuits are scalable and utilize a multi-frequency quadrature amplitude modulation (QAM) mechanism for converting digital data bits from a parallel form into a serial analog stream for communication over a chip I/O connection. The serializer has multiple digital-to-analog converters (DACs) whose outputs are directed to QAM mixer inputs, within QAMs at multiple frequencies, whose outputs are summed into a single analog signal for communication over an I/O connection. The de-serializer amplifies the analog signal which is received by QAM mixers at different frequencies, whose outputs are low pass filtered and converted back to parallel digital data bits.
