ABSTRACT:
A macrocell including a physical layer circuit includes a transmitter circuit and a receiver circuit connected with pads for differential signals DP and DM. The transmitter circuit includes a transmission driver which drives a signal line for the DP and a transmission driver which drives a signal line for the DM. When a direction from a side SD1to a side SD3of the macrocell is defined as a first direction, the transmission drivers are disposed on the side of the pads for the DP and DM in the first direction and are disposed line-symmetrically about a line SYL, and the receiver circuit is disposed on the side of the transmitter circuit in the first direction. A routing region of signal lines SLR1and SLR2for connecting the receiver circuit with the pads for the DP and DM is provided in the region between the transmission drivers.
