MAX9206/MAX9208 19-2130 Rev 2 11/10 10-Bit Bus LVDS Deserializers General Description Features The MAX9206/MAX9208 deserializers transform a high- Stand-Alone Deserializer (vs. SerDes) Ideal for speed serial bus low-voltage differential signaling Unidirectional Links (BLVDS) data stream into 10-bit-wide parallel LVCMOS/ Automatic Clock Recovery LVTTL data and clock. The deserializers pair with seri- alizers such as the MAX9205/MAX9207, which gener- Allow Hot Insertion and Synchronization Without ate a serial BLVDS signal from 10-bit-wide parallel System Interruption data. The serializer/deserializer combination reduces BLVDS Serial Input Rated for Point-to-Point and interconnect, simplifies PCB layout, and reduces board Bus Applications size. Fast Pseudorandom Lock The MAX9206/MAX9208 receive serial data at 450Mbps and 600Mbps, respectively, over board Wide Reference Clock Input Range traces or twisted-pair cables. These devices combine 16MHz to 45MHz (MAX9206) frequency lock, bit lock, and frame lock to produce a 40MHz to 60MHz (MAX9208) parallel-rate clock and word-aligned 10-bit data. Serialization eliminates parallel bus clock-to-data and High 720ps (p-p) Jitter Tolerance (MAX9206) data-to-data skew. Low 30mA Supply Current (MAX9206 at 16MHz) A power-down mode reduces typical supply current to 10-Bit Parallel LVCMOS/LVTTL Output less than 600A. Upon power-up (applying power or Up to 600Mbps Throughput (MAX9208) driving PWRDN high), the MAX9206/MAX9208 estab- lish lock after receiving synchronization signals or serial Programmable Output Strobe Edge data from the MAX9205/MAX9207. An output enable Pin Compatible to DS92LV1212A and allows the outputs to be disabled, putting the parallel data outputs and recovered output clock into a high- DS92LV1224 impedance state without losing lock.
