The MAX9206/MAX9208 deserializers transform a high-
speed serial bus low-voltage differential signaling
(BLVDS) data stream into 10-bit-wide parallel LVCMOS/
LVTTL data and clock. The deserializers pair with seri-
alizers such as the MAX9205/MAX9207, which gener-
ate a serial BLVDS signal from 10-bit-wide parallel
data. The serializer/deserializer combination reduces
interconnect, simplifies PCB layout, and reduces board
size.
The MAX9206/MAX9208 receive serial data at
450Mbps 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 600µA. Upon power-up (applying power or
driving PWRDN high), the MAX9206/MAX9208 estab-
lish 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 high-
impedance 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.

... Detailed Description The MAX9206/MAX9208 deserialize a BLVDS serializ- er's output into 10-bit wide parallel LVCMOS/LVTTL data and a parallel rate clock. The MAX9206/MAX9208 include a PLL that locks to the frequency and phase of the serial input, and digital circuits that deserialize and deframe the data. The MAX9206/MAX9208 have high- input jitter tolerance while receiving data at speeds from 160Mbps to 600Mbps ...

... If the intercon- Input Fail-Safe nect jitter is 100ps (p-p) with a symmetrical distribution, the zero-to-peak jitter is 50ps. The MAX9206 deserializ- er jitter tolerance is 720ps at 40MHz. The total zero-to- peak input jitter is 70ps + 50ps = 120ps, which is less than the jitter tolerance. In this case, the margin is 720ps - 120ps = 600ps ...
