Component | Product number | Operation Voltage | Power consumption | N# I/O needed | Needs substitution? | Quad SPI Configuration Memory | MT25QU01GBBB8E12 | 1.8 V | Max 50 mA | 4 | No, we can use HR pins | JTAG |
| 1.8/1.5/1.2 V |
| 4 | No, we can either use HR or go to 1.2V | Analog Monitor (SlowADC) ADC | ADS1217 | AVDD =3V, DVDD =1.8V | < 1 mA | 7 | Maybe. The datasheet guarantees operation for digital down to 2.7V, in HR250 was put at 1.8. Check if it is fine! | Analog Monitor MUX (x5) | MAX4734 | AVDD =3V | < 1 uA | None | They are controlled by the ADC | Humidity sensor | HIH_5031_001 | 3 V |
| None | No | Thermistor | NTC_NHQM103B375T10 |
|
| None | No | Oscillators | •371 MHz XLL726371.428571I •156 MHz 536FB156M250DG •48 MHz CX3225SB48000D0FPJC1 | 2.5 V |
|
| Both 1.8 V and 2.5V solutions can be found depending on the voltage we want to use | Clock Fanout | SI53340-B-GM | 2.5 / 1.8V |
|
| Now is 2.5, probably can be switch to 1.8, but since its AC-coupled should not matter. Check if we can remove the 2.5 LDO | Clock Jitter cleaner | SI5345_64QFN | VDD = 3.3V, DVDD =1.8V |
| 12 + n. clks |
| Programmable Oscillator | LMK61E2 | 3.3 V |
|
| Used?
| High Speed ADC | AD9249 | 1.8 V | Max 58mW/channel: 58*12 = 700mW | 38 | No | ADC_MON_VCM Buffer | AD8607_MSO8 | 1.8V |
|
|
| Bias DAC (HV Ring) | MAX5443 (DAC) + MAX14611 (Level Shifter) + REF192GS (Voltage reference) | 3.0 V (VCCA) |
| 4 | Maybe? Will the sensors have an HV ring? | ASIC clk fanout | SI53340-B-GM |
|
|
| Probably not needed | HS DAC (Vcalib_p) | MAX5719A(DAC)+ MAX14611 (Level Shifter) + OP213 (Buffer) MAX6126A41+(Vref) | 5V |
|
| Why was this chosen? Do we need the 5 V supply? | Level Shifter for Power controllers | MAX3378EETD (x2) MAX3373E_SOT23_8 (x1) | 1.8V -> 3.3V |
|

| Serial number | DS2411R | 1.8V |
