Page 7: Scope
Preliminary Page 7 of 28 4. SCOPE This document describes the SMT340, the SMT360 and the SMT380 TIM ADC from a User’ s perspective. The SMT340 is a single width TIM-40 compliant module consisting of a dual channel 40MHz, 12-Bit ADC. -
Page 8: Technical Description
Fig. 1 : SMT340/360/380 TIM ADC Block diagram Fig. 1 shows the block diagram of the SMT340/360/380 TIMADC. The following section describes this family of TIMADCs from a user’ s point of view. Reference is made to the different blocks in Fig. 1. - Page 9 When configured as a trigger ADC sampling for a specified burst size will be performed each time the trigger is asserted active. The SMT340/60/80 starts to capture N samples once it detects a rising edge on the external trigger. The amount of samples to be captured per trigger event (N) is determined by DIP Switch S2, the amount of blocks to be captured during trigger mode is specified with the LSB 7 bits of S2 (Block size is hardwired to 128 samples).

8. CONFIGURATION SMT340/360/360 DIP switch selectable options The SMT340/360/380 is set-up from two DIP Switches, S1 and S2. The different options that can be selected with these switches are shown in Table 2 and Table 3: Table 2 : SMT340/360/380 switch S1 set-up... -
Page 14: Clock Source Selection
Enabled 8.1.1 Clock source selection The user has an option of two clock sources, the onboard oscillator (40MHz – SMT340, 64MHz – SMT360 or 105MHz – SMT380) can be used or an external clock can be provided. The external clock should typically be correlated to the system clock and can have a frequency of 1MHz to 40MHz for the SMT340, 1MHz to 65MHz for the SMT360 and 1MHz to 105MHz for the SMT380. -

Page 16: Precautions
Page 16 of 28 9. PRECAUTIONS In order to guarantee that the SMT340/360/380 functions correctly and to protect the module from damage the following precautions should be taken: 1. The SMT340/360/380 is a static sensitive device and should be handled accordingly. Always place the module in a static protective bag during storage and transition. -
Page 17: Power Supply
Preliminary Page 17 of 28 POWER SUPPLY The SMT340/360/380 requires +5V, +3.3V, -12V for operation. +5V is derived from the TIM connectors. +3.3V is derived from the TIM mounting holes. -12V is derived from the TIM connectors and is converted on-board to –5V and is used for powering the critical analogue circuitry. -
Page 18: Demonstration Software
The SMT340/360/380 is shipped with a Test program (Executable and source code) for the SMT332 C6x TIM, which demonstrates the use of SMT340/360/380 with an SMT332 to capture a high bandwidth analogue signal. The following files are included (x is 4 for the SMT340, 6 for the SMT360 and 8 for the SMT380): 1. -
