The MAX9247 digital video parallel-to-serial converter
serializes 27 bits of parallel data into a serial-data stream.
Eighteen bits of video data and 9 bits of control data are
encoded and multiplexed onto the serial interface, reduc-
ing the serial-data rate. The data-enable input determines
when the video or control data is serialized.
The MAX9247 pairs with the MAX9248/MAX9250 dese-
rializers to form a complete digital video serial link.
Interconnect can be controlled-impedance PCB traces or
twisted-pair cable. Proprietary data encoding reduces
EMI and provides DC balance. DC balance allows AC-
coupling, providing isolation between the transmitting
and receiving ends of the interface. The LVDS output is
internally terminated with 100Ω. For operating frequen-
cies less than 35MHz, the MAX9247 can also pair with
the MAX9218 deserializer.
ESD tolerance is specified for ISO 10605 with ±10kV
Contact Discharge and ±30kV Air-Gap Discharge.
The MAX9247 operates from a +3.3V core supply and
features a separate input supply for interfacing to 1.8V
to 3.3V logic levels. This device is available in a 48-lead
LQFP package and is specified from -40°C to +85°C or
-40°C to +105°C.
