- Does the digital board need the analog ground (AGND)? (see 100kfps DAQ support system)
- Probably not but if there's space on connector between analog and digital it might be useful?
- Can the DC/DC architecture be simplified? Some ICs not in stock, see DC/DC converters
- Replace LMZ31530 (30A) with TPSM5D1806 in parallel mode (12A) since Vcc_int is estimated at 7A?
- Replace LT1764 with LT3083 for simpler paralleling circuitry (see power graph)
- Are the ASIC digital supply (G_DS_X) and I/O supply (G_IO_X) shared among all four ASICs?
- Do we have the CML current consumption numbers?
- Gang is saying around 20mA (15mA + 30% LVT) per ASIC TX Transceiver (for all frequencies). ASIC RX consumption is negligible
- Use FPGA transceivers for clocking the ASICs?
- Yes
- One per ASIC?
- I think one per ASIC is the best solution. Is there any reason why we should go for a clock splitter?
- Request components for Altium library (see Altium Missing Components section)
- Connectors have been requested on 2023-08-28
