SD303EVK / SD307EVK
LMH0303 / LMH0307
Evaluation Board User Guide
Overview
The SD303/SD307 Evaluation Kit (EVK) enables evaluation of the LMH0303 3G/HD/SD SDI Cable Driver with
Cable Detect or the LMH0307 3G/HD/SD SDI Dual Cable Driver with Cable Detect. A graphical user interface
allows managing the SMBus registers of the LMH0303 or LMH0307 device.
Evaluation Kit (SD303EVK / SD307EVK) Contents
The EVK contains the following parts:
•
SD303/SD307 EVK board assembly with either the LMH0303 or LMH0307 cable driver
•
USB cable
•

Evaluation Board Description

The evaluation board comes in two versions, depending on the cable driver installed:
1) SD303 with the LMH0303 cable driver
2) SD307 with the LMH0307 dual cable driver
The two cable drivers share the same evaluation board (SD303/SD307). The SD303/SD307 evaluation board silk
screen shows the LMH0307 pin name terminology. Table 1 shows the pin name differences between the LMH0307
and LMH0303. The LMH0303 has a single output channel, SDO/SDO
channel and refers to it as SDO0/SDO0
