27-Bit, 3MHz-to-35MHz
DC-Balanced LVDS Deserializer
General Description
The MAX9218 digital video serial-to-parallel converter
deserializes a total of 27 bits during data and control
phases. In the data phase, the LVDS serial input is con-
verted to 18 bits of parallel video data and in the control
phase, the input is converted to 9 bits of parallel control
data. The separate video and control phases take
advantage of video timing to reduce the serial data rate.
The MAX9218 pairs with the MAX9217 serializer to form
a complete digital video transmission system.
Proprietary data decoding reduces EMI and provides
DC balance. The DC balance allows AC-coupling, pro-
viding isolation between the transmitting and receiving
ends of the interface. The MAX9218 features a selec-
table rising or falling output latch edge.
ESD tolerance is specified for ISO 10605 with ±10kV
contact discharge and ±30kV air discharge.
The MAX9218 operates from a +3.3V core supply and
features a separate output supply for interfacing to 1.8V
to 3.3V logic-level inputs. This device is available in 48-
lead Thin QFN and TQFP packages and is specified
from -40°C to +85°C.
