27-Bit, 3MHz-to-35MHz
DC-Balanced LVDS Serializer
General Description
The MAX9217 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 MAX9217 pairs with the MAX9218 deserializer to
form a complete digital video serial link. Interconnect
can be controlled-impedance PC board 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 receiv-
ing ends of the interface. The LVDS output is internally
terminated with 100Ω.
ESD tolerance is specified for ISO 10605 with ±10kV
contact discharge and ±30kV air discharge.
The MAX9217 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 48-lead
Thin QFN and TQFP packages and is specified from
-40°C to +85°C.
