Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating onditions for extended periods may affect device reliability.
DescriptionThe MAX9206/MAX9208 deserializers transform a highspeed serial bus low-voltage differential signaling (BLVDS) data stream into 10-bit-wide parallel LVCMOS/ LVTTL data and clock. The deserializers pair with serializers such as the MAX9205/MAX9207, which generate a serial BLVDS signal from 10-bit-wide parallel data. The erializer/deserializer MAX9208 combination reduces interconnect, simplifies PC board layout, and reduces board size.
The MAX9206/MAX9208 receive serial data at 400Mbps and 600Mbps, respectively, over board traces or twisted-pair cables. These devices combine frequency lock, bit lock, and frame lock to produce a parallel-rate clock and word-aligned 10-bit data. Serialization eliminates parallel bus clock-to-data and data-to-data skew.
A power-down mode reduces typical supply current to less than 600A. Upon power-up (applying power or driving PWRDN high), the MAX9206/MAX9208 establish lock after receiving synchronization signals or serial data from the MAX9205/MAX9207. An output enable allows the outputs to be disabled, putting the parallel data outputs and recovered output clock into a highimpedance state without losing lock.
The MAX9206/MAX9208 operate from a single +3.3V supply and are specified for operation from -40°C to +85°C. The MAX9206/MAX9208 are available in 28-pin SSOP packages.
