lpc 43s70 HSADC

[HeMyFAE]

DEar LPC,

For the LPC43S70 HSADC I have a following questions for you.

1)      We are planning on using the 12 Bit High Speed ADC converter at 60 MHz data rate for high speed data sampling.  Do you have any application notes or advice on the best PCB layout techniques for minimum noise / optimum performance?

2)      For the same ADC converter, do you also have any application notes or advice on the best differential driving technique to drive into the LPC43S70 ADC Converter?

Regards,

hy

Hi Hy,

Please find LPC MCU ADC design guidelines from TN00009 document.

There also provides PCB layout guidlines for NXP MCU in BGA packages at AN10778.

Besides of above documents, you also could get some design reference at LPC43xx evaluation board below:

OM13088: LPCXpresso4367 Development Board

OM13031: Hitex LPC4350 Evaluation board

OM13040: Keil MCB4357 Evaluation Board and Internet Radio Solution

Wish it helps.

Have a great day,
Mike
