ADCM: board status

The RICH will be read out by ADC-Modules (ADCM). One sector is readout be five (5) ADCMs, where each ADCM connects to 15 APV frontend cards.

The ADCM delivers a maximum of 16x128 channels, while in normal operation the channel number is limited to 15x64 channels.

A first version of the ADCM (ECP2M-35, 8 APVs) has been tested wih a first version of the backplane and APV modules. The current version (ADCM_v2) is equipped with a ECP2M-100, two 12bit 8 channel ADCs (ADS5271), a fully operational TRBnet endpoint and a uC for slow control issues like power sequencing and surveillanca.

Data format

The ADCM_v2 delivers data with the standardized DHDR.
