Active and PassiveLDA consists of 4 parts:1. Three passive PCBs:

The 96 connectors are on these PCBs.2. One active PCB:

it is a daughter module for tests and fast repairs.

LDA Status

• LDA collects parallel data from 96 detector layers and leads the clock to each of them without a timing delay

• 80% of the LDA design is finished

• Order the PCBs in 1 week

• Firmware will be finished in 1 month

• Software is finished

• Ready to readout two full ILD detector segments with 48 layers each


Integration of CCC and LDA

1. Read-out data and send slow control data from the HBU layers as before over USB, but integrate the CCC for clock, trigger and busy

signals

2. Read-out data by USB but send slow control data, clock, busy, trigger over the CCC

3. Integrate the LDA for data read-out instead of the USB, without interference from us in the regular data acquisition

4. Firmware and software will be written by us, so we don‘t interrupt the manpower on the DIF side


Steps:


Thank you for your

attention!
