Abstract
Systems and methods for die-to-die communication are provided. A first transceiver disposed on a first die includes a transmission section configured to modulate first data onto a carrier signal having a first frequency. The first transceiver includes a reception section configured to receive signals from a transmission line. The reception section includes a filter configured to pass frequencies within a first passband that includes a second frequency. The first frequency is outside of the first passband. A second transceiver is disposed on a second die and is configured to communicate with the first transceiver via the transmission line. The second transceiver includes a transmission section configured to modulate second data onto a carrier signal having the second frequency. The second transceiver includes a reception section including a filter configured to pass frequencies within a second passband that includes the first frequency. The second frequency is outside of the second passband.

12. A method for simultaneously and bidirectionally communicating data between two dies, the method comprising:
-
modulating, using a first transceiver disposed on a first die, first data onto a carrier signal having a first frequency; transmitting, using the first transceiver, the modulated first data via a bidirectional differential transmission line;
filtering signals received at the first transceiver via the bidirectional differential transmission line using a first filter, wherein the first filter is configured to pass frequencies within a first passband that includes a second frequency, the first frequency being outside of the first passband;modulating, using a second transceiver disposed on a second die, second data onto a carrier signal having the second frequency; transmitting, using the second transceiver, the modulated second data via the bidirectional differential transmission line; and filtering signals received at the second transceiver via the bidirectional differential transmission line using a second filter, wherein the second filter is configured to pass frequencies within a second passband that includes the first frequency, the second frequency being outside of the second passband. - View Dependent Claims (13, 14, 15, 16, 17, 18)
