DEMO MANUAL DC1532
Quick start proceDure
Demonstration circuit 1532 is easy to set up to evaluate
the performance of the LTC2268 A/D converters. Refer to
Figure 1 for proper measurement equipment setup and
follow the procedure:
Setup
If a DC1371 QuikEval™
II Data Acquisition and Collection
System was supplied with the DC1532 demonstration
circuit, follow the DC1371 Quick Start Guide to install the
required software and for connecting the DC1371 to the
DC1532 and to a PC.
DC1532 Demonstration Circuit Board Jumpers
The DC1532 demonstration circuit board should have
the following jumper settings as default positions: (as
per Figure 1)
J13: PAR/SER: Selects Parallel or Serial programming
mode. (Default – Serial)
Optional Jumpers:
J8: 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)
J14: LANE: Selects either 1 lane or 2 lane output modes
(Default – Removed) NOTE: The DC1371 does not support
1 lane operation.
J15: SHDN: Enables and disables the LTC2268.
(Default – Removed)
J2: WP: Enable/Disables write protect for the EEPROM.
(Default – Removed)
Note: Optional jumper should be left open to ensure proper
serial configuration.
