QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 1151

16-BIT HIGH SPEED SERIAL OUTPUT ADC

LTC2274, LTC2273, LTC2272

DESCRIPTION

Demonstration circuit 1151 supports a family of 16-

bit 105, 80, and 65MSPS analog to digital convert-

ers. Each assembly features the following devices:

LTC2274, LTC2273, or LTC2272 high speed, serial

output ADCs.

The versions of the DC1151 demo board are listed

in Table 1. Depending on the sample rate, input

frequency and CML data rate, the DC1151 is sup-

plied with the appropriate ADC and with an opti-

mized input circuit, and de-serializing circuit. The

circuitry on the analog inputs is optimized for ana-

log input frequencies from 1MHz to 70MHz or from

70MHz to 140MHz. For higher input frequencies,

contact the factory for support.

Design files for this circuit board are available.

QUICK START PROCEDURE

Demonstration circuit 1151 is easy to set up to evalu-

ate the performance of any member of the LTC2274

family of A/D converters. Refer to Figure 1 for proper

measurement equipment setup and follow the proce-

dure below:

SETUP

If a DC890 FastDAACS Data Analysis and Collection

System was supplied with the DC1151 demonstration

circuit, follow the DC890 Quick Start Guide to install

the required software and for connecting the DC890 to

the DC1151 and to a PC running Windows 98, 2000 or

XP.
