Abstract
A transceiver () includes a receive circuit (), a transmit circuit (), a shared delay locked loop (DLL) (), and a controller (). The receive circuit () has a first input coupled to an external data terminal, a second input coupled to an external data strobe terminal, and an output coupled to an internal data terminal. The transmit circuit () has a first input coupled to the internal data terminal, a second input for receiving an internal clock signal, a first output coupled to the external data terminal, and a second output coupled to the external data strobe terminal. The controller () enables the shared DLL () for use by the receive circuit () during a receive cycle, and enables the shared DLL () for use by the transmit circuit () during a transmit cycle.
