Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
The AD8153 is an asynchronous, protocol agnostic, single-lane 2:1 switch with three differential PECL/CML-compatible inputs and three differential CML outputs. The AD8159, another member of the XstreamTM line of products, is suitable for similar applications that require more than one lane.
The AD8153 is optimized for NRZ signaling with data rates of up to 3.2 Gbps per port. Each port offers two levels of input equalization and four levels of output pre-emphasis.
The device AD8153 consists of a 2:1 multiplexer and a 1:2 demultiplexer.
There are three operating modes of AD8153: pin mode, serial mode, and mixed mode. In pin mode, switching and equalization/preemphasis are controlled exclusively using external pins. In serial mode, an I2C interface is used exclusively to control the device, and to provide access to advanced features, such as additional pre-emphasis settings and output disable. In the mixed mode mode, the user accesses the advanced features using I2C, but controls device switching using the external pins.
The main application of the AD8153 is to support redundancy on both the backplane side and the line interface side of a serial link. The device has unicast and bicast capability, so it is capable of supporting either 1 + 1 or 1:1 redundancy.
Another application for AD8153 is testing high speed serial links by duplicating incoming data and sending it to the destination port and to test equipment simultaneously.
