← ePixUHR35kHz - Megapixel Cameras
The FPGA that will be used is XCKU15P-2FFVA1760E from AMD/Xilinx.
12V vs 24V input?
TODO: Simplify the copy of the GT readout platform below
How many ADC channels are needed?

ASIC Power Requirement
Analog Section
Digital Section
I/O Section
0.6V Sink
Analog TPS
ePixUHR 140k 2x2 Detector
Voltage
1.3 V
1.3V
??? Maybe
2.5 V
Required current
10A
(= 2.5 A* 4 ASIC)
- Old digital design:1.2 A (= 0.3 A * 4 ASIC)-New digital design
????
1.6 A (= 0.4 * 4 ASIC)
[1RX, 8TX, 8serializer and 2cm clkspine : ~ 317mA]
??? (If existing lower or equal than SparkPixS)
0.4 A
(=0.1 * 4 ASIC)
System Requirement
+1.3 V @ +17.5 A
(Adding +30% current for PVT variation)
+1.3 V @ +3 A
[waiting for the new digital design]
+1.3 V @ +2.5 A
+0.6 V @ -11 A
This current is not provided by the LDO. But it passes through it.
+2.5 V @ +0.5 A
