DEMO MANUAL DC1732
QUICK START PROCEDURE
Demonstration circuit 1732 is easy to set up to evaluate the
performance of the LTM9012 modules. Refer to Figure 1
for proper measurement equipment setup and follow the
procedure below. Figure 2 shows the pinout of the analog
input header.
Setup
If a DC1371 data acquisition and collection system was
supplied with the DC1732 demonstration circuit, follow the
DC1371 quick start guide to install the required software
and for connecting the DC1371 to the DC1732 and to a PC.
DC1732 Demonstration Circuit Board Jumpers
The DC1732 demonstration circuit board should have
the following jumper settings as default positions. (as
per Figure 1)
J2: PAR/SER: Selects parallel or serial programming mode.
(default – serial)
Optional Jumpers
J1: Term: Enables/disable optional output termination.
(default – removed)
J5: ILVDS: Selects either 1.75mA or 3.5mA of output cur-
rent for the LVDS drivers. (default – removed)
2
J3: LANE: Selects either 1-lane or 2-lane output modes
(default – removed) NOTE: The DC1371 does not support
1-lane operation.
J4: SHDN: Enables and disables the LTM9012.
(default – removed)
J10: WP: Enable/disables write protect for the EEPROM.
(default – removed)
Note: optional jumper should be left open to ensure proper
serial configuration.
Applying Power and Signals to the DC1732
Demonstration Circuit
The DC1371 is used to acquire data from the DC1732. The
DC1371 must FIRST be connected to a powered USB port
and have 5V applied power BEFORE applying DC power
to the DC1732. DC1732 requires 3V to 6V at TP1 and 5V
to 6V at TP4 for proper operation.
The DC1732 demonstration circuit requires up to 700mA
depending on the sampling rate and the A/D converter
supplied.
The DC1732 should not be removed, or connected to the
DC1371 while power is applied.
