Requirement | ePixUHR | SparkPix-S | SparkPix-ED |
---|---|---|---|
frame rate | 100kfps | 1Mfps | 1Mfps |
Power supplies | 2.5V Analog 1.3V (AS/DS/IO) | 2.5V Analog 1.3V (AS/DS/IO) 0.6V (Current sink!) | 1.2V (AS/DS/IO) |
Power for each supply | ePixUHR - 35 kHz | SparkPix-S: supply/ground and power consumption | t.b.d. |
Number of GT IOs per ASIC | 10 (outputs) | 10 (outputs) 1 clock in | t.b.d |
Expected I/O speed | 4.2Gb/s | 4.2Gb/s | 10 Gb/s |
Total data bandwidth | 42 Gbit/s | 38 Gbit/s | |
Requirement | Parameters | ||
---|---|---|---|
Power supply | 24V consistent with the HR detector | ||
Mechanical size | We would like to match the ePixHRM board dimensions to reuse cooling Side entrance detector
| ||
Digital board | 2.56x5.265" | ||
Power and communication | 2.56x5.240" | ||
Carrier | 2.56x1.95 | Can we do it smaller? What is the minimum amount of components that need to leave in this board | |
System level power requirements for carrier (what are the specs for the voltage regulator and what is the number of regulators per power)
Requirement | Parameters | |

2.5V | ||
1.2V | ||
0.6V |
IO
For single ended → check the electrical specification
Functionality | IO type | Quantity | switching specification |
---|---|---|---|
ASIC control (GR, ...) | 2.5V SE | Static | |
SUGOI | |||
SACI | |||
DATA | CLM? | 40 + spares? | 10Gbps |
transceiver | 25Gbps | ||
supporting electronics | |||
enablels for power | |||
Slow ADC (current and voltage monitors, temperature sensors...) | |||
HS ADC | |||
serial number | |||
HS DAC | |||
FPGA to FPGA interconnection | requires GT+specific connector | ||
Goal is to have a decision on the FPGA package and family.
Kintex Ultrascale+ vs Virtex?
Ideal is to reuse the 300Gbps Leap On transceiver from Amphenol, unless we find a replacement that operates with single mode power supply.
Needs to be FR408HR or better
GT to the ASICs
GT to the transceivers
Power drops
Functionality | IO type | Quantity | Observations |
---|---|---|---|
carrier to digital board | 1 | Can we use smaller connectors since the number of data IOs per ASIC reduces from 24 to 10? | |
Digital to Power and communication | 1 | ||
Power communication to external power supply | 1 |
