Abstract:
A transmitter is coupled to a command and address (CA) bus. The transmitter is configurable with dual-mode support to send commands over the CA bus in a first swing mode and a second swing mode. The transmitter is configurable to send a first command over the CA bus via the pins while in the first swing mode, initiate calibration of the master device to send commands over the CA bus in the second swing mode, and to send a second command over the CA bus via the pins while in the second swing mode.
