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
