Module: lite.tbo

Name

MDL-lite.tbo_hvpulser

Title

lite.tbo: the bipolar HV-pulser

Description

  • The second iteration of the HV-Pulser of the echOmods
  • Setup? Soon a quickstart?
  • version: V0.1
  • cost:120$
  • sourcing:Tindie
  • date: 15/04/2018
  • technology: Module-compatible, Homemade PCB, ICs based on TC6320TG and NMT0572SC
  • language: Altium
  • author: Kelu124

IOs

Inputs

  • ITF-1_GND
  • ITF-2_VDD_5V
  • ITF-9_Pon
  • ITF-10_Poff
  • ITF-19_3.3V
  • ITF-mET_Transducer : signal coming back

Outputs

  • ITF-18_Raw : for the signal coming from the transducer
  • ITF-mET_SMA : for the signal coming out to the signal processing (if through SMA)
  • ITF-mET_Transducer : for the signal coming out of the pulser (if through SMA)

Key Components

  • TC6320TG
  • NMT0572SC

Information

What is it supposed to do?

The aim of this echOmod is to get the HV Pulse done.

How does it work: block diagram

Block schema

  • Pulse-P->TC6320TG
  • Pulse-N->TC6320TG
  • Damper->TC6320TG
  • NMT0572SC->HV-N->TC6320TG
  • NMT0572SC->HV-P->TC6320TG->ITF-mET_Transducer
  • ITF-mET_Transducer->ITF-mET_SMA
  • ITF-mET_Transducer->ITF-18_Raw

About the module

Pros

  • Cheaper, more robust than tobo
  • Less issues with the MD0100

Cons

  • As of today (20180305), the damper still lacks

Constraint and limits

Testing

First tests are here

Brief

Specs

  • Needed to get a couple of 10's of ns wide square pulses, both in the positive and negative.
  • Control of pulses must be through 3.3 or 5V tolerant logic
  • Pulses height must be selectable (say with a jumper?) for ~20V, 40V, 80V (for positive pulses).
  • Only power supply available is 5V

Components

Build docs

Power use

  • Needs only 5V

Components

Discussions

TODO

  • Review a bipolar design (originally alt.tbo -- but double the components and hence the price)

DONE

  • Preliminary testing

People

  • Ivan for the TC6320TG
