Abstract
Various techniques are provided for bridging interfaces, such as different interfaces for use with a host device. In one example, a system includes an asynchronous first interface adapted to transmit and receive data to and from a host device in accordance with a first protocol. A synchronous second interface is adapted to transmit and receive data to and from a device external to the host device in accordance with a second protocol. A bridge controller is adapted to convert the data received from the host device from the first protocol to the second protocol for transmission to the external device. A clock and data recovery (CDR) block is adapted to recover a clock signal from the first interface to synchronize the data received from the host device. The second interface is adapted to synchronize the converted second protocol data transmitted to the external device using the recovered clock signal.
