SMT391 User Manual

Introduction

Overview

The SMT391 is a single width TIM module. It is capable of sampling two analogue
inputs at 1 GSPS with a resolution of 8 bits. An Atmel dual channel ADC

(AT84AD001)

performs the analogue to digital conversion.

The SMT391 is a “Daughter-Module” that combines with a “base module” such as the

SMT338-VP

.

Thanks to this configuration, all the analogue circuits are on the SMT391 (on the top)
and the digital circuits are on the base module (on the bottom). This allows reducing
the cross-talk, provide better separation and heat-dissipation.

The interface between the base module and the SMT391 is digital. It is implemented
using the Sundance LVDS Bus (

SLB

).

Module Features

The main features of the SMT391 are listed underneath:

• Dual channel ADC (Ideal for I & Q channel applications)
• 1GHz sampling frequency
• 8 Bit data resolution
• Custom Clock and Trigger inputs via external connectors
• SLB connector to interface to the wide range of Sundance base modules

Possible Applications

The SMT391 can be used for the following applications (this non-exhaustive list
should be taken as an example):

• Broadband cable modem head-end systems
• 3G Radio transceivers
• High-data-rate point-to-point radios
• Medical imaging systems
• Spectrum
