82P33731/33831 Evaluation Board
Introduction
The 82P33731/33831 evaluation board is designed to help the customer evaluate the IDT82P33731 and IDT82P33831 devices.
This user guide will accomplish the following:
•
Introduce the board on its power supply and jumper settings
•
Describe the input and output connectors for normal operation
•
How to bring up the board by using Timing Commander software GUI
•
How to configure and program the board to generate standard-compliant frequencies
Board Overview
Use
Figure 1
to identify various components of the board: Input and output SMA connectors; Power supply jacks and some
jumper settings necessary for the board operations. Detailed descriptions are as follows:
•
Input SMA Connectors –
There are a total of 14 inputs, of which IN1, 2 are AMI inputs; IN9, 10, 11, 12, 13, 14 are
single-ended inputs; IN3, 4, 5, 6, 7, 8 are differential inputs.
•
Output SMA Connectors
– There are a total of 12 outputs, of which OUT1, 2, 7, 9, 10 are single-ended outputs; OUT3, 4, 5,
6, 11, 12 are differential outputs; OUT8 is an AMI output.
•
USB connector –
Type-B connector for GUI communications. No power is drawn from USB connector other than to power
the FTDI USB chip.
•
Dip Switch SW6 –
Used to configure EEPROM write protection, master or slave selection and communication protocols
between PC/GUI and the board. For typical I
2
C mode, set MPU_MODE[1:0] = 00 ('I2C ON').
•
J76 –
This is a 2x12 pin header used to set communication mode between PC and the board.
Table 1
shows how to jump the
header pairs for the intended mode. Use JP18 (described below) to set I
2
C mode by default.

•
JP18
– By default, I
2
C mode will be selected with JP18 shunted (jumped).
