# Scalable MAROC Charge Sensitive Readout
|
|
|
|
|
|
## Project description
|
|
|
|
|
|
The Scalable MAROC Charge Sensitive Readout couples a MAROC ASIC (64
|
|
|
channels each with a fixed threshold discriminator and a slow shaper +
|
|
|
sample-and-hold + 12-bit ADC) to a FPGA. Read-out by Gigabit Ethernet
|
|
|
(firmware supplied supports IPBus). Multiple boards can be plugged
|
|
|
together to increase the channel count. Clocking circuitry compatible
|
|
|
with the White Rabbit implementation of PTP.
