## Reference for PMODs designs

Reference sheets

See https://reference.digilentinc.com/_media/reference/pmod/pmod-interface-specification-1_2_0.pdf

Examples

Classical

Example stacked

PMOD_1 split in two (a+b): see attached picture above (2 boards, stacked)

#### PMOD_1a: HV generation - 3.3V in

  • Logic: SPI (x3), Enable
  • Analog design: Jorge’s
  • LEDs: Enable, SPI_CS (see below)
  • Reference design: https://github.com/kelu124/un0rick/blob/master/images/LM3478%20HVPS.pdf , or below (with correction):

PMOD_1b: Pulse control + SMA

  • Analog design: See un0rick
  • Logic: HvP, HvN, PDamp, LogicA
  • LEDs: all 4 logics
  • Reference design: https://github.com/kelu124/un0rick/blob/master/hardware/v1.1/MATTY-V11.pdf with the MD1210K6 / TC6320TG design.

PMOD_2 for fast ADC: connectors: SMA + PMODx2

  • 10 bit, 64Msps or above, ADC
  • AD8331 + MD0100
  • Low noise ampli
  • Logic: ADC (x11), AD8331 HILO (x1), DAC: SPI (x3), LogicB
  • LEDs: HILO, SPI_CS
  • Reference design: https://github.com/kelu124/un0rick/blob/master/hardware/v1.1/MATTY-V11.pdf

## Preamp (not a PMOD, but small design)

  • Amp based on OPA847
  • SMA inputs / outputs
  • 5V / GND in
  • Design as in:
