MAX9247/MAX9248 Evaluation Kit

Evaluates: MAX9247/MAX9248

General Description

The MAX9247/MAX9248 evaluation kit (EV kit) pro-

vides a proven design to evaluate the MAX9247 27-bit,

2.5MHz to 42MHz DC-balanced LVDS serializer and the

MAX9248 27-bit, 2.5MHz to 42MHz DC-balanced LVDS

deserializer. The MAX9247 serializes 27 bits of parallel

input data, 18 bits of video, and 9 bits of control to a

serial data stream. The MAX9248 deserializes the LVDS

serial input, which converts to 18 bits of parallel video

data and 9 bits of parallel control data.

The EV kit PCB has a MAX9247ECM+ or MAX9247GCM+

and a MAX9248ECM+ or MAX9248GCM+ installed.

MAX9247/MAX9248 Evaluation Kit To monitor the SerDes signal integrity, connect one channel of the digital oscilloscope with differential probe capabilities to OUT+ and OUT- signal lines from jumpers JU12 and JU13 (MAX9247). Repeat the same test for the deserializer (MAX9248) on signal lines IN+ and IN-, accessible through jumpers JU9 and JU10. Power Supplies The MAX9247 is powered by connecting PVCC1, LVCC1, IVCC, and DVCC1 to a DC power supply at 3.0V to 3.6V.
