## 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:
